Couple of ideas, open donations for:
- most armor/weps, not 1, but couple of tiers lower. e.g. donate for toc when icc is up and running; and furious when wrathful - moderate cost, milk this puppy; much lower tier quality means its ok for more people to donate for it, reasonably cheap so people want to
- lvl 60 with blues ~25 euro
- lvl 70 with blues ~40 euro
- skip que if realm is split (i bet many would donate just for this if it came out)
- make sure you add all rare glyphs, recipes, meta gems etc. e.g. mystical skyfire diamond
