I really don't see how they could make T5 any easier outside of just turning the fight mechanics off altogether. I'd have to say that if you're still stuck on T5, you just might not have enough time to play an MMORPG at all. With the 20% Echo buff, free i110 gear being handed out, and no lockout whatsoever, there's really no reason that even a DF group shouldn't be able to steamroll Twintania by now.
