I'll just list down a few things.
[Ace have you played the mod yet?]
drakes need to be faster to be more useful, faster than skyknights
[this is a good idea, i believe many people agree with you]
dark knight arrows sould do a bit more damage considering how much they cost
[what is a dark knight? please use the correct name for the units because there are many new units being introduced.]
dark hands have a bonus against buildings, giving them a purpose
[so a multiplier similar to goblins? this has potential]
birds should have less experience bonus
[what do you think would be a comparable unit to lower their experience to?]
trolls need to be distingushed from swamp beasts, regeneration seems like a good idea
[good to know another person likes this idea, a few of us like this idea already too.]
rictus needs a longer range
[this is debatable, the rictus has shorter range because it can take down buildings quicker, has a quicker reload time, and can swim]
acolyte should have some lag before it attacks to make it harder to aco drop
[good suggestion, any other aco ideas? An idea i recently thought of was to add a hailstorm attack to each 3rd tier builder per race, that way Acos are not the only unit out there]
neo dragons should be slower
[with all the new variety of units, you may not want this]
fire wagons/beast riders should not transportable, they are like stone giants, makes sense
[I could see beast riders not being transportable.... or we could just make stone giants able to be transported. I think fire wagons are smaller and should be able to tho, dont you agree? Not all units that can transport, can transport all these units. A barnstormer cant transport a beast rider for example.]
amazon knights have a bonus against flying units
[they already cant be frozen, now you want them to be neo dragon killers? Our ideas should not cripple any race, but balance units that are struggling to compete]
gods should take less time to build, dunno how much less
[this is why I asked if you ever played sages mod. In this mod, 4tier builders can assist in building any unit, including gods, and dragons and elite units. Do you catch my drift? A god can be made in no time flat with the new mod, and making gods cost less or less time to build is prob not the best idea.... in retrospect, maybe they should cost more?]
[Also note, Monarchs will no longer explode. But Gods will, they are a deity after all, but it wont be the same explosion that Monarchs had. Much smaller radius, and won't hurt monarchs themselves for balancing reasons]
all i can think of right now
