Messed around a fair bit in GA yesterday and today, but didn't get to try every hero.
-Map changes overall feel fine. I still think vehicles desperately need rebalancing; you sure as hell don't need two AT-ST, AAT, etc on most maps, and them regenerating full health is absurd. They also still need to institute forcing you out of vehicles on certain phases; Jakku was already the worst map in the game, but it's made ten times worse by two AT-ST's glitching through to the 3rd phase. The AT-ST is hilariously wasted in my experience on Maz's castle, you have virtually no clean cover and I only had success bumrushing with it to try to carry my team to capturing the point with a team that was already coordinated enough to get it. Unless they're going to physically alter the map it's pointless. I also still think that going back to the BFR2015 supremacy capture rule where the number of players from each team in the zone determine if it's being captured or not (aka one player can't contend a zone against 8 other people) honestly fixes a lot of issues.
-I continue to feel very strongly as I did in the beta that they need to cap the max health heroes can regen/heal up to. You already had beastmode players able to stay up virtually indefinitely and single-handedly cockblock entire enemy teams, and then they went and buffed Yoda and Luke lol. Senate isn't as bad but is still too strong, and in the hands of a decent player Yoda is straight-up fucking unstoppable. Teams with one or two really good hero players will completely steamroll an opposing team unless that team has good players that are ALSO the heroes that can counter.....which in what has to be at least 200 hours of play has not been my experience. I think capping the amount of health heroes could regen/heal to 50% of maximum would be a fair tradeoff IMO, it would be enough to discourage people from just hanging way back forever, but also would be fair enough to have good trooper players have at least a chance of taking down some of the more OP heroes. Right now on most maps all that really matters is which team has the better hero players, and having heroes up on the other team isn't enough of a counter on it's own. Heroes should be able to turn the tide of battle, but it's too extreme right now, and with how it's easier for most players to spawn in as a hero (which is good) there's currently too much emphasis on the actual skill of the actual hero players on each team. If that makes sense? Basically I feel like even as a very good player if I'm a trooper I'm literally just throwing my life away against a very good say Emperor, Darth Vader, etc because even if I get them down to 20% health, when I see them again in 90 seconds they will be back at full health. In BF2015 I wouldn't mind sacrificing myself against even a good player as a hero because I knew I was doing some kind of lasting damage.
-On the hero side of things: Emperor is still way too good (although with the nerf I'd say that's mostly because of his health regen/healing which I take issue with above already). Darth Vader is a fucking beast now, possibly too good. Luke is maybe a tiiiiiny bit too good but I don't take too much of an issue with it, at least not yet. Yoda is fucking ridiculous, and in good hands is fucking unstoppable and I've seen him do more broken shit than I ever saw the Emperor do. I love Yoda but he's way too good now in GA in good hands, I literally don't even want to play certain maps anymore like Naboo or Kashyyyk (unless I'm him, but you know what I mean). Phasma's staff is still garbage but I've warmed up to her a bit overall. Everyone else feels at least decent (except Iden lol) although I don't know how I feel about Fett yet, and Kylo still needs something.
It's weird, we FINALLY got a huge update I'm mostly pretty happy with what they did honestly. But in GA the increasing problems with literally one or two very good players getting a very good hero early on and just wrecking the other team unopposed is actually kind of killing the game for me. I'm on both sides of it, and I would say it's probably like 80%+ of my matches at this point. In BF2015 my friend and I would pride ourselves at being able to whittle down enemy heroes even when they were very skilled, but you literally can't do that here against a lot of the heroes, so it kind of breaks things unless you have a hero that is a hard counter to theirs and you're as good or better than they are. Honestly if team rebalancing was properly implemented, or even to the extent that it was in BF2015 (which was heavy-handed but generally did the job alright) it would probably not be as big of an issue for me, but these shitshow lobbies are just more and more of a thing it seems and hero buffs are only making that problem worse.
On the other hand I seem to consistently have different experiences than a lot of folks here so I could just be the odd duck out or have bad luck or whatever. I still desperately want game stats (how do we not have that yet?????) to see what my gametime is. I'm finding myself actually playing SA more and more which is weird because starfighter stuff is not my thing at all in games, but it's significantly less frustrating/broken and I feel like I can actually make a difference, even against a Hero ship etc.
