I'd get down on my knees and beg if it helped! :P
This guild has been a staple for me since it was first posted a long long time ago (in a galaxy far far away?).
I missed out on i3 and i4, just having reactivated my account with i5. A lot of things have changed and its hard to get solid info from one or two guides anymore. This one has always been the best and most informative; a trusted source IMHO.
