Im not going to be heavily involved in this. But since all units and routes are being looked over id like to point out 1 unit that needs a little attension and have been so since its introduction. The unit in question is the Thief.
Currently there are 4 Land Grabbers in the game.
(Sorted by Int)
Geoes
Stealth Thief
Wheelbarrowers
Thiefs
Each unit has its own characteristics. Geo's is the base. Eta 5, fastest int. Stealth Thief is stealth and allows more flexibility and types of attacks. Wheelbarrowers is the starting unit to allow more attacks to happend faster in the game. However thieves has a different approach thief fast, awfully fast with eta 3, its a prinsiple that opens more attack options for thugs with their fast eta units. However, Thiefs have 1 fatal flaw that prevents it being very attractive. That is the Cost.
Geo's have a ratio of 0.1 Which means you need 10 Geo's or: 600,000 Worth of Funds to steal 1 Acre.
Master Thief has a ratio of 0.2 which means 5 Stealth Thief ir: 350,000 Worth of Funds to steal 1 Acre.
Wheel Barrowers has a ratio of 0,03 which means 33,3 Wheel Barrowers or 1,500,000 Funds to steal 1 Acre.
However next comes my point. Take a look at the cost to steal 1 acre for the Thief unit.
Thiefs has a ratio of 0,001 which means you need 1000 Thieves or 30,000,000 worth of funds to steal 1 acre.
Now considering how early game its possible to get thieves, its original intent was to allow fast early game stealing and quick attacks. But considering the costs of buying 1 acre at this stage, or simply the cost differance to steal acres with geos compared to thieves in a stage of build up which the start of the game is. The general cost of stealing with the thief unit is to high, much to high when compared with the alternative Wheel Barrowers or Geo Phys thieves. Add the risk (being adressed here with a new spy like unit) of the fact they steal last of all stealing units. It has made the thief unit to expensive in its usage, you cant attack in cooperation with others (save for flak boosts etc), you cant use thieves much in normal attacks save to gain 3% if i recall correctly. The situation however is stil, a cost ratio differance of: 29,400,000 between stealing with geo's or stealing with thievs is to massivly different. for the same amount of funds one can get: around 13500 more Gardeners as flak, or enough Geo's to steal: 49 More acres. If we look at those 49 and continue on, its easy to see Thieves are just to ineffective currently and its way to expensive to buy up enough thieves early game to use to get full grabs.
Edit: This also removes the early game advantage of thievs since their to expensive, which leads to the usage of petrol bombers mainly instead due to its more early game advantages.
