I and many others would prefer to see both dominator and glory hound to be completely removed.
Those are the only two tasks that force players into a /ode that many actually hate.
In any mode (and with minimal team restrictions), we (could) have:
- earn souls/gold/(unspecified class as in any counts) XP
 - match a specific kind of gems including skulls
 - destroy/explode X gems (of a specific kind)
 - win X battles
 - kill X troops (of a specific kind/color)
 - do X match 4+
 
I’m sure there is something I’m missing, and maybe not all tasks are equally as open but all of the above can be done more or less anywhere.
