…is mid tier artillery. I played ~30 tier 5 & 6 games today and maybe 4-5 of them had just one arty. The rest had either 2 or 3 arty's and at least one of them always was the mighty shit cunt incarnate 105 leFH18B2.
How does the experience of playing those tiers look like? Well, you're driving your stock tank with inexperienced crew, you get spotted, immediately hit with an arty shell for ~200 damage and tracked. You use you repair kit and immediately get hit by 2 more shells, tracked again and left with maybe 200HP. You don't have another repair kit, so you have to wait those 10 second for someone else to come along and finish you off. GG.
Of course after a game like that you end up getting maybe 100 exp, so you're not getting any closer to unlocking new modules, but truth be told, they won't help you too much anyway. I have no idea why WG is allowing matchmaking to look like that, but it seems like someone there is about as out of touch as all the people who are telling newcomers they should stay at the lower tiers to "gain experience".
