I was farming her for many months on Al`Kabor for her mask. I got AHR's mask (which is far better) before Katta's ever dropped.
Group was 65 RNG, 65 ENC, 65 CLR and 65 WAR.
65 RNG 500 AA - VT geared 5k HP unbuffed used 2 hander to avoid pulling aggro.
65 WAR max AA - EP geared 7k HP unbuffed, used pet proc weapon and 20/17 wep with 150DD proc.
65 ENC 120 AA - FT6 in mostly in Ornate PoP gear with some Velious stuff and I put on detrimental focus.
65 CLR 350AA - Max FT, Ornate PoP geared with Aid Grimel earrings, Halls of TEsting quest gear and some VT rot loot.
ENC would pacify Lcea's guards and pull her to ZI where RNG, CLR and WAR were waiting. WAR and RNG were fully debuffed.
During the pull, Katta takes some crazy pathing. I used this to my advantage to cast slow/cripple/tash on her so she'd arrive in camp fully debuffed.
ENC would then zone out, letting Katta stand in position for awhile and then slowly walk back to her castle. During this time the ENC would zoneback, call and buff pet.
WAR would then tag Katta (she was usually near the entrance to her castle at this time) and run back to the corner by the ZI. I popped evasive just before she hit, attacked with RNG and sent in the chanter pet. Do not use charmed pets here. Nearly all the guards respawn every 30 min or so and you will lose your pet.
To deal with the unresistable charm, I followed the same strat that "manaburn" posted below, with one exception: I let the RNG take the hit while my WAR was charmed instead of the pet. I found out that if the chanter pet got charmed, I usually could not regain control of it and invis wouldn't kill it. I used the pet as DPS and as a very last line of defense against cleric summon if both tanks got charmed.
This strat worked really well. I used pillage enchantment and recant magic so I always had a dispell gem hot. With casting haste focus, they cast in 1.6 sec and 2.1 sec.
I also had a Nullify Magic loaded on the Cleric. When the ENC was reslowing and crippling, I would use the cleric to spam the MT with dispell, just in case he got hit while the ENC (my primary dispeller) was casting debuffs.
The biggest killer on this is when Lcea procs multiple charms in a row. If you aren't quick on dispelling the tanks, she can get both tanks and the pet in 4 or 5 seconds on lucky procs. Once she has all tanks, she will summon the cleric and it's game over.
Keep the tanks constantly dispelled and it's a sure win, but a long fight. About 45 minutes each time using elemental DPS weapons on the tanks.
Mana was never an issue but did dip down a bit on the CLR when the RNG had to tank for longer periods due to back to back charms.
