Well, I think it's funny that the early gun's shells only travel so far! My KDR with the 25mm french sniper would have been much higher had the shells not simply disappeared at 250meters. Do you know how many kills the RenaultFT, D1, Hotchkiss H35, AMX 38 & D2 could make if they traveled longer than that? You could sit with your crazy french armor & bounce everyone all day LoL!
If the maps weren't so big, radio range wouldn't be important. In early tiers its important & makes you buy the tier 9-10 radios ASAP in tier 4-6.
