Why can enemy grenades take you from 100% to 10% if you are barely in the explosive radios (also the grenade indicator needs work, it's not very visible) ? Why is Blast Shielding even a perk when explosion damage is so high that it's benefits are completely negated ? Why do explosive barrels not have an audio q when they are about to explode? This one is my biggest gripe, nothing like a barrel exploding behind killing you instantly, it's not challenging it's cheap. Rant over !!!!!!
