I cleared H UK today with my team, finally. Wiped 2-3 times on first boss and once on second boss and twice on trash, but not too bad. I must have wiped 15+ times last week on first boss, and didn't really do anything different this time -- just a weeks worth of getting quest/rep gear for my team made the difference. Once you get past the first boss the rest isn't too bad, tips above definitely were good!
