My fav part of this discussion is people using % values in most creative ways they can, because it makes the actual numbers seem big, exaggerating the values, when in fact its very small(for comparison, at exact same distance, conscripts on the move have 6,9 DPS).
I call it snek maneuver.
Couple that with the fact that you don't move and shoot at any other units then retreating ones(reason to close in with tommies does not exist) and you'll have half of that DPS.
The numbers are small because those are the numbers used in game. A stationary Gren squad at long range has 9 dps and 4.5 when moving. 3 dps is a lot of difference in this game because the numbers used are small in general. A huge percentage increase has a huge effect - it's that simple.
You're placing emphasis on the "size" of the numbers as if it actually mattered. If we changed the values in game to models having 80 million hitpoints and doing 16 million damage with a bolt action rifle, then we'd actually meet your criteria for "numbers seem big". But nothing has actually changed - you're simply using "low values" as a red herring.
This is pretty much the most Katitof you can ever go.
42.8% buff is gigantic. It's uncalled for. If a unit does 1 damage in a game where units have 1 health, and its damage increased to 2 that's a 100% increase. You can't magically wave it off and say "oh it's only 1 point of damage", people are over-exaggerating as usual.
Like I said, you've reached peak Katitof.
