I've been reading the forums for a while and have been patiently waiting the arrival of 5.0. I've had some grand ideas of changing alot of things to make the game more single player based, but then i realized i have no experience programming/coding at all, so my ideas would be pretty much impossible to achieve. I was hoping someone experienced could point me in the right direction of anything that could help like websites/books etc.

Some of the things i was hoping for was....
Creating hybrid classes ie. Ranger/Enchanter or Warrior/Necromancer, basically giving a single class the ablities of 2 like keeping the hp/ac of a warrior and the spells/specializations of the enchanter. In addition to creating hybrid classes(if this is possible), unlocking class options that are not available ie. Dark Elf Rangers or Ogre Paladins.
Scaling down difficulty of mobs so that they can actually be soloed by a character that is even conned, like having a lvl 55 character actually be able to solo a lvl 55 mob, with great difficulty, but making it possible.
Increasing regeneration rates for all characters, perhaps percentage based like 5% of max hp every tick.
Lastly i was hoping it would be possible to increase exp gain like perhaps making the exp gained from mobs 1.5 or 2x more then eqlive.

If anyone can post stuff i can research or become familiar with to help me do these when 5.0 becomes available I would greatly appreciate it. Thank you in advance.
