1. Better REAL/BOT player ratios - I'm the only player in my league (day 3 start) - MAIN issue for me.
2. Cheaper PACKS. - they are ridiculously priced. 1 token = 1 Pack...come off it. Id suggest you bring pricing down by at least 50% and offer better bundle packages. IE 50 green, 50 Red & 50 Blue (who wants blue but w/e its a bundle deal) for 50 Tokens (at current pricing).
3. Facilities too long - Make the upgrades more expensive, and make the upgrade times more reasonable. Plus multiple builders seems obvious. Make the swine pay 50 tokens for another builder if they want it. But speed production up.
4. Level 4 for negotiations? Come on, who the hell wants to wait 4 months to unlock a feature of the game. Transfers is the key to this game obv. Open negotiations up to level 1. Let the spenders spend and enjoy, instead of boring them so much they leave. Give players the option of turning off incoming negotiations if they so wish (and cant already).
5. Friendly's - Basically how it is now is fine, however you need an option whereby the challenged player can RISK injurys/GAIN rewards etc as well. IE actually compete.
6. SHOW the whole transfer market - If I can see it all by refreshing constantly, whats the point of hiding it, make refreshing easier (ie in game) or just show the whole thing.
7- Let me GAMBLE. I want to play friendly's for prize money. Both teams put up a pot and winner takes it ($/TOKENS). This should be rolled out across the board. There should be a waiting list of challenges. **** there should be KO tournaments. Server by server is fine, should be a piece of piss to set up.

You can counter the level disparity by charging the high levels more entrance. IE a level 1 guy creates a game for $100k, another level one guy could take the challenge and put up 100k, a level 2 guy could take the challenge but he would have to put up 200k (or level equivalent - im assuming the money value doubles with each level, so follow that protocol.) If the level 2 guy wins he wins the 100k, lose he loses 200k, the level 1 guy can only win 100k regardless. That's just to avoid high teams giving money to low teams. I guess you will chuck a 1 token fee on creating the match/entering the match. Meh needs a little thought.
