The only things I can think of to add at the moment:
*Agreeing with Margoth that members of the group should recharge when needed, especially in lowbie groups. Low-level healers do not have the skills and abilities to keep everyone topped up without needing to recharge themselves like an endgame healer can.
*Disagreeing that Sorcerer's should "bubble the whole group if a Sorcerer healer isn't present". DPS-specced Sorcerers/ Sages bubbles can be energy expensive depending on skill points spent and level. Perhaps bubble the tank at strategic times if possible.
*In the Damage Dealers section (or possibly General), I'd like something along the lines of "Use knock backs carefully and only when needed" added. It can be extremely annoying when a healer/ DPS knocks back a whole group before the tank gets aggro... Or knocks an enemy away from the tank/ melee DPS, or out of an AoE attack.
Keep up the good work.
