Hi

You give walls 100% resistance to poison
This leads to problems when playing against Rampant Fixed
There is a "juggernaut" faction, whose only attack is an AoE that heals allies and damages enemies with poison. Since the walls are indestructible to poison, this area creates a healing zone from many juggernauts, in which the biters can't die
Two problems:
1. Lags from many AoE effects of biters and turrets
2. When a critical mass is reached, the walls are destroyed by other types of biters and this crowd goes to destroy the base

If you wanted to remove the effect of destroying walls with the Rampant arsenal rocket, then you can specify that the AoE effect affects the “not-same” side.
If you wanted to increase the strength of the walls higher than in the settings of the rampant itself (60% resists to posion), then perhaps you should limit posion resitance to 90-99% ?
