Thing is a bit different for NA and that is the blocker, EU battle died almost two months ago when there were issues with autobalancer and never recovered.
Personally i don't mind wiping the game in fact I advocate for this for some time already. Strategus reset didn't really bring any players as they left before it happened, at this point crpg on EU side is dead for over a month. Battle hardly gets more than 10 players. I played like two days ago wiht 7 or 8 guys and no one joined, the day before we had 5 vs 5 siege, for like an hour no one new appeared on the server and we just left.
Even DTV is getting less and less players with every day.
I would say wipe, it can't be worst than that, fuck the looms and levels when you can't even make a proper use of them.
Raise the starting level to 30, forget about the "grind" part from peasant to something usefull, if someone wants it, he will retire and get the low lvl grind.
On a side note, would be nice to have some kind of happy hours, it does wonders on Mercenaries module, 100 on siege and around 50-60 players online. DTV needs a reward adjustment, some time ago someone suggested to disable upkeep and gold gain there it's not a bad idea, reward for winning a map is crazy high needs lowering.
There are some that log in just to play dtv and it's fine, people enjoy the game in a verry different way, and that is the strength of it.
For battle I'd advise to get small maps like the one from there :

Things that I listed are not a really hard task for someone talented like Professor. You may keep th NA database, but if possible EU needs a reset.
