In Proving Grounds when selecting dragons major (not sure if it happens with any others) about 50% of the time my mobs do not change to the appropriate difficulty.  As a result they have huge HP and it is basically unclearable due to the time it would take where as when it does spawn properly I can pretty much one shot everything.

Nillipus` Stampede of the Wee (Bard Song) uses alteration which bards do not naturally have.  Feel like this skill should use an instrument skill check.

Noticed the issues about targeting quest NPCs and such in T10 from the latest update, and wasn't sure if this was a similar issue since I am not currently in T10.  So just posting here incase it is.

Summon Noobie Merchant (Reward Item) -  The vendor which is spawned from this can't be targeted via /target <name> or /target id <id>.  Says no spawns matching when attempting to.
