Failthread is fail.
What you just said is absolutely not true. I have seen VenGyr block towers/stand out many times.
There's no reason to do it really, even though he has that hp. It's his hp, not yours. If you want to do good in battles, you spend YOUR skill points in that skill.
So okay... if you say your suppose to work as a team or whatever, that's true. But lets take 2000 as the average hp... that means you can take about 7 hits before you have to move to the back line. I don't see any reason for VenGyr to take more than 7 hits (around 1750 hp) before moving to the backline. If he wants to, he can do more, but if he doesn't want to, that's his call and not yours.
Think before you make a crap thread like this one.
