Yeah, I liked summons variety from DOS1, picking the right summon at right time, and having multiple of them from different schools...
here its problem that you have specifically spec into summoning for it to be really good and waste your memory slots with buffs (without buffs its pretty useless). This makes summoning bit of all or nothing school, because it is really, really strong as main spec, and not really that strong when sidelaning it - its just not worth 3-5 AP just to create+buff your mediocre incarnate unless you have really high summoning skill.
Also not able to pick targets for your totems is absolutely bullshit
