The Cap regen and mana regen back in the day was capped at 15 during classic, kunark, Velious, Luclin, PoP, even maybe into GoD. I was in a guild that wasnt totally completely current raiding content, we use to raid Luclin PoP zones and Clerics / shamans always kept close tabs on what their worn FT was until Sony changed the names of "Flowing Thought" to be changed to "Mana Regen: XX" it was at that point the mana regen cap and HP regen cap was removed. As long as the Aura of battle, and Flowing Thought name tags remain the cap should stay at 15 cap. Fungi caps you. Start looking for a aura of battle belt, mask, and bp that have good resist / stats and rep that fungi!
So if your capped at 15 (fungi) then thats your max worn regen(or should be)...Id try to get more aura of battles and stack those and keep your resists (like vindi bp, the mask, and belt to get 6HP regen).
Check out these posts it seems as it might still be in effect.

Appears the cap is still 15 for both mana and HP, but the higher your INT/WIS (for mana) will kick up your cap, along with AAs/levels will move it up but in our era, we are stuck at a max of 15 for both. Problem solved.
