Hi, Is my understanding correct that Vanilla factions have been buffed to a quite significant extent when compared to Sectorial? Not only they do get Harrises now (granted, for Reinf. only), but also the Sectorials do not get additional Harrises. So you have to chose between fielding your Harris in the main group, or later in reinforcements. Is that correct? Also - I noticed HI Vanilla gets 2 Harris now (wtf?)
Almost correct, you can have a Haris from the start, if during reinforcements deployment you choose to form a new Haris then the existing Haris gets disbanded.
Don't be too jealous, it's literally impossible to form 2 separate 3 man Fireteams with the current setup of reinforcements, so one of them is just a glorified third Fireteam Duo that you can only use for reinforcement troops.
