How much time does the tier 1 and 2 upgrades for the eldar and space Marines take from start to finish to happen is it doesn't tell you in game as I would like to know, so to have anyone that can answer this would be very much appreciated as I already know that the orks if your building Waaag towers which take 30 seconds to build to go up one tier.
if you have the resources to build five at the same time it only takes 30 seconds for them to be fully tiered or two minutes and 30 seconds if done one after another if you only have one builder.
