Icons are hard to read, in need of a total redesign.
Its unnecessarely hard to differentiate between an assault, tactical and devastator marine. Upgrades for 1-3 health/damage for infantry and vehicle differ only in small + symbols, when they should be INSTANTLY recognizable when you look at them.
They need to be of different colours. Same goes for doctrines, all i see in the selection screen is a mess of red/bleched bone pictures that are almost the same. The difference between "invigorating slam" and "charging slam" is tiny spikes on the circle.
Something needs to be done here.
