Yes I agree, but what about those major battles which you cant avoid? I can name many. Two, probably the hardest part you'll come across is the entire Sulanessalar battle when you save it from destruction. Even I had big toubles with it and every part member was maxed out with exp.
I recommend that you use Lure tactics in this section. This involves becoming invisible and fireing off one arror (or something) and make one of them follow you. I assure you, fighting 1 Iron Golem is hard enough as it is! Imagine fighting 3 or 4 at time!
