1). Kill EoE, kill EW and kill all other spirits.
2). STOP OoA! Rather easy if EW get's killed as soon as it pops up.
3). Stop holding hands if they have alot of AoE pressure, dooh.
4). Keep Weapons of Warding on number 7, keep Aura of Stability (and guardian) on 8, keep Make Haste on 7 and 8.
5). Indeed good mesmers also divert tainted and interupt some hexes, but OoA should have priority! Period.
And it's bye bye heroway, if everyone does his or her job. A lucky dazed on 7 will be drawed by 8, RC is godly, channeling is godly. Most of the times holding hands and faling to do a key job makes balanced teams fail against heroway. If everyone pays attention that won't happen.
Last rule, ignore We Dont Accept's post, his tips on beating heroway are.. weird at best. DF is sold.
