The last DMC games I owned were 1~3, I never really got into 4, nor the DMC game (reboot). If DMCV is stuffed with MTs when the prior entries weren't, then yeah, that's really shitty. Especially if it's "pay for power" upgrades. My stance doesn't change depending on the game or whether I like it.
I've also agreed many times some games are far worse than others with their implementations, but the second any game (well, especially $60+ ones) offers an ability to pay for power I think that's out of line, even if the game is fairly well balanced.
