Yeah, people claiming this to be a net positive are people who weren't planning on staying with the game for a long time. Why are people so excited for MLs when they don't like PVP? I don't get it. This is a net positive to whaling. People without 5 stars still have to pull out of a super diluted pool. If people are barely playing the game and at silver in arena, sure, net positive bc you MAY get to play with the one pretty ML unit.
Going by the very vague notes, when this change is implemented everyone who has a ML 5 star that got nerfed will switch to have the "one" that is the most broken still. Whales will have every unit and all GvG will be ML Vildreds/Rueles/Aras. However, there's still no mention of compensation for people who don't have ML 5 stars or ML Banners (since they haven't mentioned removing mystic summons), in that scenario, everyone here is still going to be rolling on covenant summons and mystics praying for luck.
If they had just re-tooled the ML system to only need like 4 Gold Transmit Stones, have every side event give out a transmit stone on top of the artifact grind events, have raids drop gold transmit stones as a low % (instead of ML BM), have a 30-40 pull ML Pity and lower the rates of getting a ML 3 star by like 10-20% and divy that up between 4/5 stars, it'd make the chances of getting MLs way higher without spinning the high ranks out of control.
Overall, I don't think this is super healthy for the game, but for people that didn't have high aspirations, sure, you might randomly get ML Ken during your daily summon. The only way I see this working is if they nerf the living shit out of ML 5 stars. ML 4 stars being in the covenant pool is fine, it's just the 5 stars in their current incarnation would run rampant and make the game generally way more unfun.
Additionally the main thing I'm cranky about isn't arena, because arena is a shit show in Champion as is, is GvG. GvG was a place of salvation and fun. Now it'll just be ML 5 stars running rampant on every squad in the top 20. (My guild is currently top 10 :poggers:)
