Keep in mind that the relics are totally customizable, and they will always be up to date with new content as it releases. The relics are there as an immediate tool for raiders to have access to before gaining the tomes for Aelina's weapons or even the weapons at the finale of each coil, assuming those stats are even worthwhile (because who wants parry on their axe? Forget that garbage.)

As for your lance, the best you can get is crit/det and the only lance that offers these stats in a worthwhile quantity is the Dreadwyrm lance at 37/38. Your Longinus however can see 53/36 as you trudge toward your t13 loot. As for the Ironwork lance, the det is nice but it comes with a massive accuracy boost. If you're already at the accuracy cap (which you should be if you're getting these weapons for raiding) then that lance is utter garbage compared to the other two at that level (the relic and DW)
