Yea, it isn't much. But, unless you are homebrewing some grenade, normal frags only have about Blast (3) which means you need 30+ agility to dodge them if you are the center of the AOE. 10 less Agility for every meter away from the center.

See, that doesn't make much sense to me. Both in terms of mechanics and in a more narrative sense. Grenades IRL, even our modern ones not the advanced ones of 40K, are lethal for tens of metres - no dodging that. Plus 30 is still under human average of 35, meaning that...soldiers in the guard must just dodge frags for their training...

I'll look into it more in later combats, as for now it is what it is.
