That's looms and high skill level fault, you should blame shields for that.
With elite cav shield and 4 shield skill, my shield can barely survive 6 arrows from high level/loomed archers like Blackbow. I'm not talking about low shield skill or cheap shields. Elite cav is among the best shields and 4 shield skill isn't bad at all.
Of course, similar thing happens with that same shield, loomed and 10 shield skill like kinngrimm has. It takes 10 GLA hits to break Masterpiece Elite Cav Shield with 10 shield skill.
That is why I've opened similar thread a month ago, trying to find best solution for this problem.
If you ask me, best thing would be to buff shield skill from 8% to 12% damage reduction but also to change the way you increase shield skill. One shield skill per 6 agi and many things will be fixed.
There will be more people with shields, because they will be able to put 2-3 points in shield and have excellent shield. Kinngrimm will have to spent just 5 points in shield but he'll also have 20% less damage reduction (now 80%, after 60%). It's not loss for him neither, because he can put 5 points into IF or WM.
