I don't have alot of experience with Thudds, but their achilles heel is they're a
FW item with
FW rules. Unless it makes its way into the Codex, people will bitch about it. Keep in mind, I'm
FW Friendly and have no issues with it. The only reason I haven't used it in the past was because I preferred my Suicide Vets.
Don't they shoot every other turn, so 3/6 shooting rounds?
I'm so very curious to see what
GW will do with the next
IG Dex. With new Ogryn minis and
PF not getting the extra attack, the pendulum could swing pretty hard in their favor with an improved statline/ point cost. (I could be waaaay off base so let me know)
Attack of the pendulum could really save Mortars as well. They're blast so auto hit right

S5 and BWB will make a killing off mortar bits.
Regardless of the rule changes and potential Dex changes, some things will always remain the same. BS3 only hits half the time. HRoF weapons like heavy bolters will always have a place, especially against Orks. The
HB/ flamer squad may even become a staple for a platoon's picket line.
I'm really liking Heavy Weapon squads with
HBs. 280 (naked
HQ) points for 27
HB shots/ turn can make alot of failed cover/armor saves over the course of a game. Add a 2nd or 3rd platoon for redundancy and Bob's your uncle. For every squad, your getting a
LR worth of shooting (no ordanance ofcourse) with out the worries of a lucky hit destroying it in 1 turn. Not to mention, their mortality rate will improve with
V5. Feel free to pick this apart as I'd rather not waste time and effort if I analyzed incorrectly.
