An healer that lets its Eos heal is no more lazy than a tank that aggro things and then wait the things die maybe pressing 1 1 1 sometime.

Then healers have duties as Bray hard, that they are the only ones pressed to do their job. DPS there just sit and do their rotations until mobs die. Tanks just aggro a pack, then sitting there popping up cooldowns when they ready. Healer have all the hell out to keep tank alive and one error is a wipe.

Got the impression some community thinks the healer just a commodity that follows around. No wonder tanks running away and start bosses without healers and/or buffs on. This negates the MMO common sense I made in the years, as example wait buff and healer in range before start aggro. On top of that, then blaming healer because he wasn't so fast as tank on running ahead. This is L-O-L.
Also saw i100 Tanks doing noob things as go aggro without even checking if buffs on and healer in range. One also started aggro while I still were in first CS.
