I like to think that my view on things is a little more complex. There are parts where I'm willing to make concessions, but I really do think the game'll benefit from having a roster for each role where they can perform comparibly at their main role. There are ways to help classes distinguish themselves without making one clearly superior to the other for content. It really falls to aesthetics, mechanics, rotation, and in this case, heal types available per class.
I have played WoW since vanilla, but I'm not exactly a fan. Otherwise I'd be gobbling up the garbage they've been calling "lore" for the last two expansions.I can only assume you're a big WoW fan... healing in that game is a joke, they tried to do exactly what your asking for, these "smart heals" you basically just spam and it heals the whole group.
Maybe you forgot, but the way smart heals work is that they have a target limit, unlike AoE heals which affect everyone in range. A Curaga can hit 8 people in a full party so long as they're in range with no pentalties. Chain Heal can heal up to 4 targets, loses effectiveness for every additional target it hits, and will always pick the targets within range that have the lowest HP. That alone creates a difference in how you play and prioritize your heal targets, because by design you have smart heals or have AoE but not both within the same class.
IMO WHM was fine because it played more like a healer in a modern MMO like Rift, WoW and CoH rather than the FFXI version. Besides, we know when the sh*t hits the fan any healer worth their salt will start their healing rotation and not even look at the DPS abilities.I think whm was over-powered in 1.0 dmg wise compared to blm's but I kinda like the fact I had the option to DD I guess and do decent at it. People should have the ability to DD and off-heal in the same way I could heal and off-DD I guess.
