The best solution will be:
Limit those gems to be use at 40/41 gears only. High levels indeed need more armor to tackle para and eye gem. But not for twinks. They already been maxed out with gears been provided and armor boost or damage reduction pets like littlebear, Frist, abaddon, singe.

More armor for warriors will be chaotic at levels below 15. It's almost impossible to kill warrior with pure armour and 3 heal skill build. Adding more armor will simply ruin the pvp because nobody going to die and all u see at pvp is just trash talk and bla bla bla.
