You gotta love the it's nothing wrong with summoner people.
1. Bane is useless unless it's a big mob.
2. Pet can't stay alive during solo gameplay or maq, why ummm Idk.... Oh yea no way to heal them.( some people act like they forgot we solo to)
3. We're punished way to hard for dying.
4. When you summon bahamut he takes aggro with him so titan is useless at that point and your running around in a circle until he gets it back or the target dies from your dots.
5. Titan is very weak to actually tank without sustain. And before anyone say something I challenge any tank to try tank with no armor, weapon, or any form healing and see how long you last(rip if you're stupid enough to try it).

But sheep when follow anything SE does because that's what sheep do, If SE say nothing wrong with summoner than the sheepple won't see nothing wrong with summoner.
