If you got Enginering and you have not gotten yourself a second pair of boots with Nitro enchant, then i got a tip:

GO GET THEM!

It's brilliant in small BG's. "oh FC inc, but it's a mage with 18k hp. I'll just nitro to him and global the alliance." I just got a second pair of wrath boots with the nitro on it and i allready love it. I guess in Bg's like AV it's not that usefull, but in sota or WSG i imagine it to be quite helpful.

Follow does not break, so that's no problem.
