Invested time and money is irrelevant when discussing issues in the game, these are things that affect everyone in a negative way
Bugged Classes:
Still waiting on a fix for the Noir & Guardian class.
Elemental Dungeon:
Untouched, outdated rewards that provide no incentive (besides EXP)
Power Arena:
-They are re-running a poll to see how many people want to change PA time, their reason for a re-vote was that not enough people voted last time. (Do they know the amount of active players?)
-Myself, I will no longer attend any power arena until i see a change made (Either make it more accessible/attainable for everyone or reduce the HP on the talisman)
-We're onto our 8th season of Power Arena and nothing has been changed as of yet.
Township Battle:
Untouched, outdated rewards that provide no incentive.
Bring back clashing valley?
All we can do is (as a community) implore the GMs and hope they listen to our suggestions with more attentiveness
