Why am I so weak at 90? Help!

What I suggest is getting the "Weaponskill Path" Weapon from the Trials of the Magian. It has a decent base damage and as you skill up your scythe skill (or GS skill for that matter), you would also be able to work on a better Scythe as you go. So, start out with a Reckoning and after completing 6 Trials, you got yourself a Reckoning +2 with 10% added dmg to any Scythe WS. It's an excellent scythe to be using in the interim if you're going for anything better.
