The ironman challenge could be something yeah.
17 85s? I have 1 and Im tired already! If you find the game boring, try twinks. Level 70 twinks are very popular on EU. Rank 1 in 2v2 takes only 2k rating in some battlegroups, why not aim for rank 1? 19s are active on EU too, I think on US 70s & 80s are pretty popular.
