1. A wizard tower: This would allow your channeler to cast spells in any combat (like MOM) It would make your main character vital worldwide (like a immortal channeler should be)
2. A "bank" of mana for your wizard: Mana that would continue building until you spent it allowing your channeler to cast more powerful spells more often (like MOM).
3. Better town buildings: You should have to build different types of barracks for different soldiers (I like the sion temple thing). I think its kind of crazy that a brand new settlement can crank out your best soldier as long as there is metal in your global reserve. You should have to build a armors guild and a cathedral to produce paladins (like MOM) Also, only towns with magic crystals could build magic armies, it would make every city important and special.
4. Of course better more interesting spells: Enough said
5. Better combat mechanics: Every soldier is basically an upgraded peasant. I really love the mechanics in MOM where every defense, attack or resistance stat had a 30% chance to succeed (it would get better with experience)
6. Soldier experience:
7. Better rewards and guardians: It was a lot of fun to try to build an army to take some great resource that was guarded by death knights and then be awarded with a new talent/ability (like MOM)
8. Every race should have certain types of armies and buildings to produce: Every other game around (HOMM5, MOM, AOW) has set armies you have to build up to create, please get rid of the generic peasant, oh wait he's on a horse, so now he is a knight mechanic. Trying to build up to the point of getting a level 5 "or whatever" unit keeps you pushing the turn button.
9. Last please don't make all spell books researchable: Why MOM was so re-playable is because you had to start over to try chaos magic, not just research it. (PLEASE Brad don't do this it would make every game the same. By the end I would have all the spell books, wouldn't everyone? So who cares what you pick at the beginning. Also spell book picks should cost a lot more or maybe you should have to buy them by level (if you want blizzard, a level 3 spell, you would have to buy 3 water picks) Like MOM.
Yes I do like MOM (top ten game of all time on almost every game sites list) and yes I wish there was a remake so now I will just slink off and boot up my DOSBOX and play a very old game. In all honesty I really do think these would help the fun of Elemental and Brad did say they were going to change a lot so lets give him our best ideas.
