Try turning on debug the show options for the various sets, and the log, and see if you can tell which one (and let me know please, so I can disable it for any 2h weapon).
Edit your [MQ2Melee] section of server_char.ini
Turn these from 0 to 1:
ShowAbility=1
ShowAltAbility=1
ShowBash=1
ShowCasting=1
ShowCombatAbility=1
ShowProvoking=1
ShowRange=1
ShowSkills=1
Save, and reload if in game: /melee load
Turn on debug logging: /meleedebug
When you see it spamming you in EQ window, see if you can tell which one MQ2Melee is trying to use.
