And lets put the FS bit this way, you can corpseskin and pull off that combo. I had a friend hit me with this. I had 120 HP and was corpseskinned down to 60 fire, that combo dropped me to 14 HP. If I didnt have chugging I'd be a FB away from gray. Without being corpseskinned, I had him do it again and at 70% fire it dropped me to 24 HP. Again this is 100% effective unless you're lucky enough to hit the parry mage. I could go on but there's really no point.
Your logic is slightly flawed when saying that people can exp/fs/eo/ps too easily with parry being so effective.
A parry mage can't output that kind of damage, I know, I play both necro and parry mage.
There aren't enough available skill points to be necro/parry with the scribe to get the dmg bonus. Not to mention, to be an effective parry mage you need to sacrifice intelligence for a minimum of 80 dex (after items, which results in additional SDI lost).
Instead of complaining about dmg dealt by necro mages that get exp/fs/eo/ps off, maybe you should switch to a faster bow when someone casts 7th circle spells?
I know you play an archer because you like hitting only 3 keys, but come on, change your tactic a bit.
And concussion is overpowered, on my dexer I tested it and I can do 9 concussion blows in a row, 10 if I get consecutive mana leech off.
