My first main was a spines/sr scrapper. Had terrible endurance issues so i didnt take any toggles in /sr. I also had SS, SJ and teleport.
Biggest might have been quitting the game after i10. Was quite pissed about crafting, especially when i had 2 accounts full of ho/sho'd out characters. Now that im playing again i realize how simple and painless the crafting is here after playing MMOs like Darkfall, POTBS, and GW.
