Character specific lag

My templar (level 13) has been suffering extreme lag spikes, but other characters on the account play fine.

Tested several other characters, and templar in/out of parties, restarted client, etc.

Played all day on other toons, no problem (latency in low 200s or so). Played templar and it spiked regularly up to 1K+ (hung a few times).

Toon - Akkeron.
