ideas for Tag game

Hello,

i'm the maker of the tag game Orcs&Elves.
Now i'm planning to make an expansion called Never-ending Forest.
I'd like to get some new ideas.
definitely planned are 2 new orc profiles and many upgrades and skills and the possibility to choose profiles as an elf, but i'm not already sure which profiles they sould be able to take, so do you have any ideas ??
completely different ideas are welcome as well ;)

An ability u need to research for orcys like shadow meld

Cause campin would be fun :D
