I know a lot of folks like to micro-manage their pet (and for some of the heally-rard (see what I did there?) endgame funzies it's needed) but for most content, g'head and let Eos be free!

A bit more on topic; SS + E4E (on tank) + Rouse + Aldo is a solid starter for large single bosses. This will allow you to go offensive and push those DoTs early in the fight. Toss Succor up for adds/blanket AOEs.

If you havnt gotten Thaumaturge up to 26, now is a good time. You'll WANT swiftcast for all the lvl 50 stuff you'll soon be doing.

Curious: ps3/4 or PC?
