Dump the alacrity relic ASAP. If you have no other choice, hang on to it for the endurance, but once you can, grab something else. There are fantastic new relics for 200 daily commendations, so I'd recommend saving up for one of those. Also, as was said earlier, if you have any items which are blue or below level 50, consider picking up a cheap orange crafted item and filling it with the epic rank 22 armorings/mods/enhancements from the daily quests on Ilum & Belsavis.
Alright. I got it relatively cheap from the recruit vendor. Should I just get another one for shield or do you recommend something else?
The only blue items I have are my two implants and the shield (both are from the recruit vendor). Everything else is purple or orange.
