I joined a game today were my team had lost 2 relics and the third, anguish was on its way to our side to end game. thankfully it helped us turn it around. It fell a few inches short of a holder and killed all the enemy one by one. and eventually my side won. So a team can lose the advantage and the game can be turned around at the last minute.
I really would like to see how a one shrine version of Shrine dom would work on this map.

That pretty much sums it up for me. Theres always the chance that the other team will keep spawncamping at e base after they have pwned the start, but bad games can happen on any map and I think theres no good way to fix it. If we take down the spawn time to, say, 10 secs we would propably see extend marathons very often.
And for making the map bigger. I don't have the tools nor the skills to really modify the map, so the only possibility is to change the map to a bigger one. Brangulvs Dam has a square field at the bottom of the map and Angrims Bastion could be a good option too. The problem is that on those maps there is no wall around the gaming area, so it could easily turn in to a big long run.. And everyone would need to DL it allover again. And the holders can't be made solid, sorry, that would again need the modifying tools and skills..
Bottom line is that I think that map works good as it is, and one should never ever go mess up with something that works :p.
