Not really. The m8 barrage range is 80, but the pack Hwiz barrage range is very long,guess what? It's 120m.
Also the m8 have much lower angle.It is a wipe machine which can have 30+ kills when being used properly.Surely they have poor range but they can auto fire while the rocket artillery has a long cooldown of barrage. IMO the USF is fine when they now can use calliope.
what i mean is that the barrage is bad and that leaves the auto fire which has short range for artillery.
both the pack howitzer and m8 are very effective in direct fire but neither are very effective as artillery, which leaves USF with a lack of solid artillery. the lieg on the other hand is good in both direct fire and artillery roles so it's possible to do both.
