I actually had more fun doings 2s on my shaman than 5s. Just make a few basic macros, i used /cast [target=arena1] hex and arena 2 for the other. start with an AS hex or 5 mael instant hex, once you have some damage going. should force a trinket, then pop defensives, wait for hex, then instant hex and onehit macro. gg

i never spent much time on it, but had a good w/l ratio while capping. can shoot up to 1600 pretty quick.
