I am really looking forward to your Paladin and Sorcerer release.
I was hesitant to play with the Ranger mod at first as I don't like changing the game too much from what the developers originally intended...I mostly like adding more content with the mods I use. In any case I tried the Ranger and LOVE it. Great addition. Doesn't stray at all from the realm of elemental. Imo, I do think the level up's are a little overpowered compared to the others....but I suppose that balanced out in the fact that you need a ranged hero to make it so.
For the Paladin:
I am curious as to what you've done for the Kingdom styled Paladin. You mention D&D which is an excellent basis of comparison. The D&D's Paladin is very defensive with healing.....like a cross between a Defender and a Healer. I am wondering how you intent to pull that off without diving too much into the existing features found in LH's defender and mage (for healing).
For the sorcerer:
I am really curious how you plan to pull this off. LH's mage is already a strong mix of D&D's wizard and sorcerer. Do you plan on rejigging the Mage into a Wizard?
In any case, you have my support in the development of these and when the time comes I'll pitch in with the balance suggestions. (unfortunately I'm horrible at coding and graphics so I can't help you on those fronts.)
Lastly, in the Ranger's thread fsemprini was kind enough to modify the TraitPathChoiceWnd.dxpack file such that the Ranger was on the same level as the other path choices. I am hoping that the Paladin and Sorcerer can be added to that list....not sure if 8 can go in a row....
