My personal opinion is summoner doesn't need a tank pet, titan-egi always was a badly implemented pet, and the new implementation just further reinforces that Titan-Egi could be deleted and I doubt I'd care. Putting survival utility on a pet with a button that directly competes with doing more damage is already a bad enough idea, and the class has far bigger problems than not being able to solo mobs 100% safely like it could before. As for pets having aoes that can hit things around your target, it's entirely possible and reasonable to maneuver singular adds away from other adds, so I'm not sure this is actually a problem as long as you're patient enough to give the add enough time to move away from others. Hell, I've gone through all of ShB without my pet accidentally pulling anything that I wouldn't pull accidentally from Deathflare anyways.

Also, only the Faeries are the same. Ifrit is your single target damage pet, Garuda your aoe damage pet (ifrit does do aoe damage, but it's still primarily single target), and Titan is a noob trap since the shield is almost always the worst thing you can do in a given situation as it denies you both the damage from EA 1 and the ruin 4 charge.
