But that could be the way to go maybe. Some people around here claim that Recon Support is quite strong at 1vs1, mainly because of the cheap price ot this bundle.
Changing this bundle would impact 1vs1 in a lot more negative way than 3vs3/4vs4. Imo it would have more of a positive impact at the big game modes actually, because you want to have more than one Reserve Para squad for sure and you want to drop them behind enemy lines to support the assault of your mates. The howitzer just hinders you to do that.
If Airdrop bundle would be changed (swap with MG for a cheaper MU price or remove support weapon completely) you could add some versatility to Greyhound and add additional effects like vision and capping speed to infantry with active Raid Tactics ability. In 1vs1 this would make up for the nerfed bundle and keep the commander at the same power level, in 3vs3/4vs4 this commander could get attractive with this changes finally. A more versatile Greyhound (recon for example) could even see some late game action at 3v3/4vs4, if it has to offer some unique options.
well i agree that such a unit swap (pack vs mg) could work out if it is accompanied by buffs in other departments, like the greyhound as you proposed. but that would require a rather expansive overhaul of the whole commander tree, not just a couple of tweaks here and there to make individual units more viable/less situational.
i just don't think this would be the right way to go, especially considering it would be tricky to get the balance right in one patch (which for what we know isn't unlikely to be the last one on the horizon for coh2).
some slight changes to the greyhound, be it in the form of better utility, a bit more AT or earlier arrival, would be my personal preference for the next patch. and if really necessary, some additional way to call in recon paras besides the combat group drop could be implemented as well. i remember there was the suggestion some time ago to give radio beacons the ability to call in paras once the cp requirements are met, and for me this would probably be the best way to squeeze this into the commander without using one of the precious ability slots. this would also give the beacons a bit more utility while, at the same time, allowing some sort of counterplay against paras being dropped behind the frontlines.
