Can only assume people prefer this from force of habbit.
Objectively speakingl the only instance "green numbers" popping up as they did is of value is when viewing the results of an offscreen units fire.
Far more rational to to be able to follow the xp gains of onscreen units simultaneously contributing in a firefight.
Otherwise its say:
3 cons vs 3 grens.
Models die.
Green numbers.
No idea who killed them or just earned xp.
But Ill drop the topic, since it seems to be a sensitive issue for the old guard of vCoH, whom I otherwise have only respect for.
Why do you need xp numbers over your guy to know he's vetting up? A giant flashing gold star pops up when a squad gains vet. You can't possibly miss it. What we need is a visual indicator of stuff that's died in the fog. It doesn't have to be XP numbers. It could be word art for all I care but there needs to be some sort of feedback and XP numbers made plenty of sense in COH1 since they allowed a player to know exactly what he killed (based on the amount of XP floating up from the fog).
