STR is one of your weaponskill modifiers (30% Penta, 50% Wheeling) so this lance is definitely going to have an impact on damage. You can theoretically skip it, especially with Level Sync, but it's worth an investment if you want your numbers to climb and while it's not cheap, like a lot of the higher level DRG gear, it's cheaper than its equivlents.
I know ppl want there stuff to sell but they need to think about when they are under cutting ... begining of the month this thing was still a little over 200k now it's below 100k WTH!!! there is no way this thinkg shoudl be selling for this cheap oh well guess it's just economics of the game.
