45 troll shaman reroll? and casual end game solo question

[Hakubi]

I have a 45 troll shaman that was my first character on the server, haven't touched him in years because the tear price went from dirt cheap to insane. He's got max True Spirit faction (but no epic). His gear is garbage except for JBB, gobbo earring, 5/55 rings, and clay guardian shield... the rest is banded. My main question is, should I save up for a fungi and reroll ogre?

The second question: I don't have the time to commit to raiding in the foreseeable future, but what content could I be soloing if I did take him to 60 as a NON-raid geared troll in gear like this (w/ torpor but NOT puppet strings):

I know I won't be doing WW dragons in that garbage but how much does slow trivialize end game shaman farming targets for the crappily geared? or should I be tempering my expectations to cliff golems...
