I'll avoid the wall of text and try and keep this as simple as possible.
With new gear being added on a fairly regular basis (And some of this gear being end game gear), it's about time they took a look at adding more options to epic augments.
I'm not asking for anything that's OP, just maybe remove the stuff that no one is ever going to waste 20-30 epic tokens on and add in a few abilities that justify that particular grind.
When all is said and done, Epic items should be the pinnacle of Gear and a lot of it is utter trash even when slotted.
Just some examples below of what I'd personally like to see, but at this point in time all I'm really after is that they review the whole system and bring it up to date with what's going on now.
Remove things like +1 to spell focus of a specific school. Does anyone ever use those?
Add options for Striding. Doesn't have to be the full 30%.
Add in a healing amp option (Even 10% would be more usefull than some of the junk that's already there).
These are just basic ideas and I'm sure other people would have a more extensive list. As said earlier, all I'm interested in at this time is that it's looked at and put under review for improvment.
