I don't know anyone who would want the chat logs to show protect/shell/spikes type buffs being applied to each player individually especially considering prot/shell need to be re-applied every 4-8 min.

BUT

DoT should be shown in the log, does it show if "player XYZ is poisoned" now? I feel like the log is a mess and I have learned to rely on visual UI cue's to do my mage duties. I do miss the day's of FFXI where my RDM or BRD was always on enfeebling duties and used to have a very very tidy log with enfeeble's showing in a very NEON like color.
