ok. ive read the whole thing.. and i want to say... OMFG!.. finally someone amde it/ started it. (here comes my whole story of playing tons of mmorpgs and private servers pf those xD.. -_-..)
ok. here it comes:
1. for the monsters spawn:
a) let it be as fast as in originall AL.
b) when player enters a zone let only then monsters spawn -> less lag
c) Avoid double boss spawn when 2 ppl enter a special raid-zone
d) Challenge-zones with imba monsters for ppl for want to test their equip after long hours of crafting
2. Server, bugs, cheats, exploits, etc.
a) in the original AL you can use this zero-time for skills bug. so my idea is: really good protection against such things OR --> skill-double-speed-buff

(should be available like a potion or a separate skill)
b) will you allow more gms!? it could make the game easier and funnier
c) bots?! allowed or not?! (or even better, make your own server bot

or allow 2 hours max per char to bot.. just my opinion)
3. game system
a) no lvling-cap, it means you can go to lvl 1000 (even if it will take you 10 years of playing only without sleep and no eating anything ^^)
b) allow skills form other races from the 100th lvl form extra-special trainers in the save zones between uber-hard creeeps so noobs cannot reach them

c) starting gear/money -> ive seen this in an other game (wow):
after starting a char on a server you get (your char has it in inventory) starting potions and special server gear (like Mal's Team - Shirt: +2% atk speed, etc.)
4. items
a) if 3c) = true, then let ppl choose on their own in the char-making screen(gear OR money) or add an option on the web-site (which is of course mysql-based and is in contact with server

)
b) more custom items (ideas post in the extra-forum, lol)
5. make a web-site with donation-option and NOW!!!!
a) donate, id like to
b) donate, did i say it? oh..
c) yes, i want xD
d) other should to -. -!!!!
thats all.. for now
