There's nothing a healer wants more than to be ignored so they can free-cast multiple big heals on their team. That's not something the opposing team wants. You have two options, a) CC the healer, or b) pressure the healer with damage. Do either and the enemy healer won't be able to heal their team effectively. Healers have to be dealt with in some way or your team will likely lose.
Yeah, Anytime I see healers, if it isn't just one I single out the biggest threat, Priest being first, paladin being second, shaman being third In my opinion. I'll catch the healer out of combat and sap him until DR causes sap to be immune then I engage, even if I know I'm going to die, depending on the situation. If my team can take down at least 2 dps and push back an inc/zerg I know I've done my job.
When I see EFC escorts, first I sap the healer once, if the EFC hangs around, I keep sapping the Healer until DR causes sap to be immune (if the EFC keeps going I sap him instead) Once the healer's immune I move to sapping the EFC. The whole point in this is to stall them from the EFR. The longer I can keep them in mid, the more vulnerable they are. I keep sapping the healer/fc when DR goes away and I keep a little ways ahead of them to keep them from getting too far ahead of me.
The only time I really DPS is to pressure heals, to peel for my FC if my Sap DR is up, or to kill a flag carrier (most of the time I'm too busy locking heals to DPS FC's but there's moments).
I just always thought that's how rogue is useful in this bracket so that's how I play.
I just lost my nerve earlier when I had this EN shaman talking shit to me when with 3 flag returns and Alliance healers on lockdown I was the backbone of the team.
Is there anything I should do differently? Other than ignore people and a possible attitude change lol.
