in oly I use : tallum + DS health + instant zelot/bison/barrier => I win very fast (and w8 some min for skills recharge , then win again )

I play in the same server as PaaGRIO from this forum does and he gave me some advices about oly...

Dyes: -9 DEX +5 CON +4 STR
IC set
DS+health
ogre totem all the way, but vs destro and other slow enemies use rabbit +cripple and kite with rage and blaster.
Remember that ur forces must be always max (8 ).
Start with hurricane or blaster, then use rage till u get again 8 forces.

Vs glads, there isn't a big choice:
ogre totem and use blaster,'cause ur range attack (blaster) has more power than gladi's blaster. And try to keep distance between you and the gladi.

Vs debuffers, like summoners (those fcking cubics)
use riposite stance ( a.k.a R.I.P. stance =D )

In hard sitations use barrier+bison+zealot.

When you and the enemy have both low hp, you can use Doom as last hit, but its quite risky, you may get stunned and lose the match.
