Ok, let me see if i got this right. You have Rotos, Lilitu, Arbiter, Rhazin, Nethril, BEK and some really good epics and you considered Lanakis as your "first good champion"? I bet it something to do with my bad English, maybe i misread that part.

I am sure you will max her anyway, because, yes, she is good, that one is for sure, but about your question can she fits in your CB team, my uneducated answer is... maybe. Depends of the way you set up your team. If you have your team in speed tune set up, she will mess thing up, But my guess is you didn't set them in strict turn order and speed tune, but it is all about max your damage until CB wipe you. In this case Lanakis can take Nethril's place. Why i think so:

1. You can't remove Jareg, he is the one with Atk Debuff and Ally Protection,

2. You can't remove Rhazin, since he is the one with Defense Debuff and Weaken, And eventually for removing CB buff when under 50% HP.

3. You can't remove Septimus, since he adds too much value to your overall damage and he backs up Jareg, because Jareg can't keep up that Attack Debuff all the time by himself. Same for Weaken and Defense Debuff from Rhazin.

4. You probably can't remove BEK, because you rely on him as much as damage dealer as healer.

5. Nethril seems like the one you can replaced without losing important utility.

But can Lanakis  turn meter and Rally skill can make huge difference for you... that one is up to you to test.

As I read your post I thought, "What!! "your first good champ?" I have been playing for 6mo now and don't have any of those champs you listed. (probably cause I'm F2P)

Since I never met any of your champs I can't provide much help with your CB team make up, but Daering broke it down nicely. 

I just broke 3M on Normal with the help of my newly acquired Bulwark, and beefing up my O. Brawler.

Had to throw my 2¢ in.......Good Luck to you Gerkules

Hi all! U understand me wrong.
