The changes have been implemented now.
We will take all ideas (especially from
http://forum.beta.grepolis.net/showpost.php?p=1959&postcount=4) into consideration for the next balancing updates.
yay \o
A little bit offtopic: Why do ctpdule and fisherman post with the same ip? Why do they make the same spelling mistakes?
i lol'd 
i few more ideas from my side:
1. reduce the effect of city-wall, you have around 3x more losses between wall 25 and wall 0 (if you go with 60 horsemen against 100 swords, you lose 20 at wall 0, and you lose the fight at wall 25). it's way to hard if someone has 1500 BHP def in his poli (and is a good player) to get him, because of anti-timing-rule. You need more than 3000 BHP off-units to beat him at wall 25, even if you use only the attack of his weakest defense. Catapults are no option aswell, because you need a nearly clean base to get a high effect on bringing down his city-wall. Poseidon-stacking isn't possible aswell anymore.
2. Change the "only 1 divine spell per unit-move" please. The defender hasn't any chance to spell the enemy unit's with Hera, because the attacker is always faster at buffing them. And in the late-game you always have enough favor (at least with 1 god) to buff them.
3. Buff Hoplits attack from 16 -> 19, because there is no non-mythic unit with good pierce-attack.
4. Show researches if a spy is successful (not necessary, but better for calculating attacks or free population. Aswell you maybe don't colonize this towns with crap-researches). Another idea is to choose at spying, between normal-spy and research-spy (maybe research-spy needs 20% more silver to get through or sth. like that)
5. if you attack someone with only ground-units and trapos, the defender needs only 1 ship to kill all trapos in a sea-fight. It's a little bit annoying, if you are unlucky at anti-timing-rule and the defender times 2 biremes between your trapos or finishes 1 in that time, that you lose all the trapos is a seafight then. I would like to see a change of this.
6. let mythic units support everywhere (i know this is a problem with the thinking of letting athene-units support in hera-citys, but at the moment mythic def-units are underrated. You can also attack with mythic off-units everywhere but you are not able to move your def when you got attacked, so you have to build normal units for def to be moveable between cities).
7. Reduce swordmen distance-def from 30 -> 27.
8. Reduce earthquake to 450 favor, that you don't have to stay at the favor-limit if someone needs this. Then you can use his other spells without worriing about the need of earthquake in the next 3 hours.
9. Reduce the requirements of Olympic games, Townfestival and Theatergames to Academy lvl 29 or 28. The idea behind that is, if your building-loop is full and a zeus-bolt hits your academy this can be really annoying.
10. Higher the effect of market place above level 20 to 1000 capacity per market place up to a total of 20000 instead of 15000.
11. Reduce Light-ship building time a bit (around 10%)
