I have been out of the game for almost 4 years now, and this post highlights the major reason I left the game.
I took my dark/regen scrapper to lvl 50. I had a beautiful build based on soloing mobs. I had trouble with bosses, but I could always get help for that. Once I got IH, i was a solo mob thrashing machine. I was getting xp like mad on +2 lvl mobs. The glory in this build was that I didn't need any additional healing. I'd kill one mob, be left with 15-25% of my HP, and by the time I ran to the next mob, i was back at 100%.
My EPM, (Experience per Minute) was phenominal!
Then they took IH, and made it useless, and completely gutted my build.
(Addditionally, they screwed with the Mind Troller abilities, and I had to scrap the build idea's for my next toon)
I was so mad I left for WOW, and didn't look back for the next 4 years.
I'm back now, but only until I get my x-box. . .
