My reason on why VZTZ was horrible (balance wise) is cause resist system was just garbage.
I would run bard song with 300 + MR and get snared/rooted/mezzed/stunned you name it. Meanwhile druids nukes were resisting so easy. It should be the other way around. Nukes land but its harder to land those overpowered spells.
During classic/kunark all you needed really was 80-100 MR and you wouldn't be snared/rooted/stuned/mezzed so easily. My bard had 3x that and was still being controlled. Another problem i had was with the Hitbot... it was WAY to huge on live you had to stand right in front of the person to hit.

Look how far my enchanter is and hes still hitting my paladin LOL. This made jousting take no skill. Anyone dueling each other was like a toss up.
Another problem i had was the delay on turning attack on while jousting. It seemed off compare to live. Also when you cast a spell and leave attack on it shouldn't act like your still attacking your target and once the spell is off you should be able to hit right away.
