1. HP super upgrade for all players largely cancels out the whole point of PVP coin update (an elephant and mouse fight will always end up as win for elephant even if Mouse has sharper stick). Girl atk and player HP has become more unbalanced than previously.
Making every Tower Fight as World Boss Fight is not enjoyable in the long run for any player.
2.Fun and intriguing part of Colosseum event was - to match up your cards with different player options. Now huge player HP just crushes this fact and in addition, you need luck at start as well lol.
LUCK WTF? Remove coin toss from Colosseum fights. Colosseum fights are NOT Tower PVP fights.
3.Provide free gems (atleast 150) in girls event, so that large number of players can finish event goals for gold in easier way.
NOTE: It is best if you could rollover the recent update changes to old mechanism as these changes are prematurely applied in my opinion (there are still lots of girl card with pending ability upgrade).
Now, I no longer have same excitement for new event start and only reason to not quit the game is because of the amount of time I have invested previously.
