Obviously this doesn't address my point at all since it's responding to my specific example without considering the overall point. You may not always be able to slidecast, depending on the mechanic's design. The point is that other casting jobs have ways to gain mobility when they need it and summoner does not.
But if we want to talk about healers... white mage has lilies, sage has phlegma and toxikons. I don't play the other healers and so I won't speak for them. However, I did look up clear PoVs of p12s with both AST and SCH, and saw neither of them actually slidecast there.
Feel free to show an example if you have one.
