Some suggestions for Treaty (That won't affect normal games!)

First of all this is for treaty players, please don't complain if you don't even play the game mode. Secondly don't make comments about how devs won't balance around treaty game mode, look through the recent patch notes plent of things have been changed purely because of treaty mode.

I am almost a treaty only player since I pretty much first picked up aoe3 9+ years ago, I prefer it because I enjoy the late game battles with maxed out units, this said I do think there needs to be some alteration to treaty in its current state.

My main problem currently is that even though you can spend 40 minutes building ur base and preparing for the battles of all battles the game can still be ended within 5 minutes with a hard rush or cheese strategy (getting rid of the cav box glitch somewhat helps with this). I have a couple of suggestions for improvements in this area that will not impact rush games AT ALL.

1. Larger map size, pretty self explanatory and it can be easily done, maps are always larger if there's more players than a 1v1, for treaty I think a good change would be making the size of the map as if its 2 more players ie in a 1v1 the map is the size of a 2v2.
2. Larger build radious from TC, in its current form its just too small, there's not enough room to build a proper fortress. IMO the ideal scenario would be enough room to have ur eco/main base + enough room to build a solid FOB. I think a possible option would be giving players access to a whole 1/3 of the map (going from their start side) and that leaves a solid area for no mans land. There definitely needs to be a sweet spot, I do not want to go back to the nightmare that was NR HM where players would have 20+ walls between themselves and the enemy.
3. A global buff to buildings/Global nerf to siege damage. I'm really not a fan of the idea that 20 calvary units can take down a section of wall within seconds, It makes no sense realistically and I don't think it makes sense in the game. I think the primary option for players to take down buildings/walls should be artillery and everything else should be nerfed. This will make the game more strategic instead of just spamming units into a base. Players will have to prioritise sending siege artillery and protecting them. Possible solution would be a global nerf to siege damage for units that aren't arty, or a global buff to building HP. Atleast maybe just walls/forts/towers other buildings are in a good spot.
4. Fair starts. Its pretty frustrating when a palyer has access to a TP and you don't or even worse if they have access to the ocean and you don't. Point number 2 would address this in a simple mannor

Let me know what you guyd think. I do not want games that go 2+ hours but I think they're currently a little short.
