I think it would be better that:
1) stoneskins or ironskins are casted only if an enemy is not seen, because this way mages would lose their round, instead of casting a ADHW or whatever to finish the brawl.
2) potions should be used only if enemies are seen and in range/attacked; there is no need to use a bought potion when your cleric can simply cast Cure Critical Wounds; it would be better if potion-drinking was totally removed, to avoid accidental round-losing.
3) Remove the follow-player1 routine in the party-buff script, so that you can explore/ambush/whatever with him, while the other guys are finishing a secondary brawl.
4) if possible, add the HLA buffs (globe of blades, aura of flaming death, hardiness, resist magic, avoid death, greater evasion (the last three maybe, if the 5-rounds-duration is enough)
5) add a sing-the song routine (I don't remember, but I think there isn't one)
6) reduce the duration of the auto-buffing spell, or, with correct timing, it would be really easy to use it as a free 1-round improved alacrity+ 0 spellcasting time.
