I have to admit, I really haven't had issues with TE spamming either, even when undergeared. As long as the PLD establishes hate, usually with a flash-scorn-flash combo, they shouldn't have aggro issues when spamming TE if they weave in flash like, once every 3 TEs if it comes to that. But...then again, this is the DF, so yeah...usually the worst of the worst are found there.
