ok so im kinda new to tds i have a golden tower, (cowboy) and most of the important towers for strats. (ranger mini farm gcowboy ect) but im so bad at loadout building i barely get use out of them. is it normal to not get full upgrades on towers in hc? because everytime i play at the final round i can never seem to get max of all towers, let alone 3 and idk if im doing something wrong. (ive been using milbase,ranger,turret,commander, and mortar) But also i have no idea how to get a good one for coin and xp farming, im only level 109 rn and REALLY want merc base but also really want engineer and the gold towers. which ones would be better to go for first? golden towers, all the regular towers, or engineer?
