Hi all. Wondering about the ability to '+5' enhancements. I see that the boosters are quite expensive. Where will I get the best bang for buck doing this? For example if I have 2 generic recharge rate IOs in hasten - is it worth boosting them? What about boosting damage? Are the gains really minimal? Or maybe money better spent elsewhere. To note my main is a fire/fire tank (already have all IO sets and t4's so looking for what to do next)..... Thanks!!
