If you are 20x someone's score you should be able to kill them, regardless of routes, especially in alliances, solos however, all you need to do is only buy up when you'll be online for a while, plant, then buy units to kill their attacking troops.
It's not whether you can kill them or not you obviously can. It's the fact that due to the adren rush the attacker gets either x2 or x2.5 bounty
So a RPG can rush die completely and still profit.
What the suggestion is, is to remove/lower the retal limit to add a bit of risk to the rushing
Just drop the x* amount you get from the adren rushing..
As I said before in the BigBoyBounty
I like the idea of something usefull for a -2 rush.. but a 2.5 bounty is just insane..
imagine..
rank 200 has 15m sins
rank 1 has 100m CW's 50m TD's 100m CG's 70% bounty for title +5 base
rank 200 sends sins on rank 1, -2 rush.. 75*2.5= 187,5% bounty!
rank 200 can loose his total army, and still walk away with a profit...
2.5* bounty is just too much..
1.5* and 1,75* is more reasonable imo...
