I imagine it would be frustrating for the Germans getting constantly mortared, but it's just as shitty if you're allied and the first two flags have still yet to fall, you're putting up a great defense, and with all the tricky hidden passes, underground tunnels and alternate routes, some German (usually an SL) sneaks past and spawns his whole squad in that two-story building on the corner of the road that connects the Allied mortar flag with the church flag. Within two minutes, anyone that spawns at the back two Allied flags is dead within five seconds of spawning, because the German squad has picked up all the Allied pick-up kits in the area (sniper rifle, No4 w/ satchels + S-mines, Boys rifle w/ Thermos nuke, etc.) and the admins on neither server do anything about it. This is a-okay on one server, and completely ignored on the other, even if it is technically against the rules and obviously against the spirit of them. Even though backcapping isn't possible, this still happens on half of all rounds on Fall of Tobruk.
Not that there is really anything anyone can do about it. The more underground passages and building mazes this map has the better, but the Allies are fucked nearly as hard as the Germans are on this map. Maybe swap one of the Allied mortars for some more cool pick-up kits? This map has some of the best ones (like the Boys + Thermos nukes, the No4 + satchels and S-mines, and my personal favorite, the Thompson with 20-round clips with HE grenades and Binocs). Maybe lose one mortar but something fun, like a Lewis gun with smoke grenades, a repairman kit with the 20-round Thompson and a wrench, an explosion-man kit with a pistol and no main weapon, but two satchels and two nukes/sticky bombs. Two kits of that kind of thing (on different parts of the map, like the multiple places for the Thompson/HE grenade kit, Boys/thermos kit, No4/satchels/S-mines kits) would be very useful and in the hands of a competent player would kill just as many Germans over the course of the map as the mortars would, but (and this would be the key) they wouldn't be frustrating Germans nearly as much as continued mortar slaughter is.
