Just an idea I'd like to see some if there's any discussion value in. Should citdel upgrades scale up with map size or player numbers?
Just been thinking that the citidel upgrade dynamic can be quite different in a 5v5 compared to a 2v2. Plainest example I can think of is the currency upgrade but it applies to most upgrades. Currency upgrade 1 costs 1800 gold and gives +4 income per player; in a 2v2 it takes 225 secs to pay for itself but only 90 secs to pay for itself in 5v5.
Same for creeps, the full upgrade path to giants costs 16.2k, that's 8.1k per player in 2v2 or just 3.24k in a 5v5, the bigger maps also have more portals so you get roughly similar creeps-per-demigod for each upgrade on a large map with lots of players as you do on a small map with fewer but at less cost-per-demigod.
This gives the effect that in smaller games you choose items or citidel upgrades carefully, whilst in 5v5 as a team, you can have your cake and eat it by getting both.
If it should scale, at what point should it are the current costs "just right"? I.E are the current costs in 3v3 or 4v4 most balanced?
How sharply should it scale too, I.E should 4v4 upgrades cost exactly twice as much as in a 2v2 or just a fraction more like 25%?
