Just played a few matches of Breakthrough on Tsuru Reef, in all the matches there were atleast 3-4 people on the defending team sitting at spawn just spamming mortars. How is that fun or balanced?
We literally couldn't do anything because you can't reach them and there was no highpoint on the map where I could pick them off from. All I could do was run into their spawn zone, pick one off, run out. Rinse and repeat, but that usually resulted in me getting shot by somebody else on the enemy team.

Well...yes, they suck. Yes, they have unlimited ammo. Yes, you can counter mortar them. Other than that, you will take a pounding.

Allowing those things to be placed inside enemy spawn was the worst decision ever. It has to be reversed, but dice will never listen.

You understand that some of the boats have AA guns, that also act as mortars, right? That is literally how some of them are used. If you have them, plus medics using mortar launchers, it can make for a rough game.

Use the Support's MP APS... it stops mortar shells.

Just 2 of them before self-destruction.

You don't have access to boats until the final sector on Breakthrough. Kind of one of the reasons it's a bad map on that mode, doesn't really feed into the theme of this season's maps. Would have been better to have had access to them from the start (that and the attackers spawn point being on a ship).
