There's nothing wrong with experimenting. I experimented with EVERY set possible for enhance right when 4.0 was released. I was ready for enhance and knew it was probably going to be the only viable spec, even though I had gear ready for every spec. I tried int/agil build, I tried full fang, I tried int/crit, I tried everything. People experimenting now is pointless when I've already done it. I come off as a dick but I'm trying to save people time in situations like this because I've already tried all the options. I was the FIRST person to actually come up with the right set up. Oh, I even tried armor pen 2H and haste set ups.
Just because I don't find the game fun anymore doesn't mean I dismiss everyone in the bracket I played in for 4-5 years. If you'd been playing this bracket before 4.0 you'd know I try everything and you'd take my opinion.
This is what I learned from all the different shit I tried. Goblin Enhance Shaman were the MOST viable kind of shaman in the bracket for premade offenses, using the gear I choose. That's it. Simple.
