If you make a scion sorc you're asking to get your ass whooped. Sorcs go full ashtal, reason = I have 11300 hp (with a BG top, without a party) and last episode I hit knights my level for 3600-4000 max. Why would you want more damage, you'll just be a pushover in any real pvp (involving stun, halt, mass pvp fights)?
I speak about last episode now, but I fought all scion sorcs, their damage was pretty but they die faster than I can say peanutbutterjellytime. Doesn't matter if someone hits you harder, when you recover more than he does.
What I do, and what I suggest for sorcs, is that you make an extra pair of gaunts/boots and fill those with scion stones. If your target is fully party buffed and hard to kill, you switch equip and pummel his ass.
