In general I like the idea of strike teams and a dedicated sniper unit in particular. However, the play pattern that arise from an abundance of Sniper Teams especially when used as a support to an gunline style army are not always enjoyable. List building is less diverse because Sniper Strike Teams are somewhat of an requirement for many army concepts. Changing their weapon range to 5 was a good first step but not enough.
My main problem with them is their resilience - in particular their ability to hide the extra model behind LOS blocking terrain to make them unkillable with a single attack (and always turning on heavy cover). Together with Medics reviving the lost model and Tactical on ARCs Snipers are simply to effective.
So what would I propose? Inspired from the Counterpart Rules I'll change the Heavy Weapon Team bullet point from
QuoteIf the unit leader of a unit with the heavy weapon team keyword is defeated, replace one of the remaining minis with a heavy weapon mini from an equipped heavy weapon upgrade card.
to
QuoteWhen the unit suffers wounds, any mini can be assigned any number of those wounds regardless of whether the attacking unit has line of sight to that mini.
Combined with the standard rules that the Leader always dies last that means no more hiding for strike teams. You can always destroy the entire unit in a single attack without the ability of medics to bring them back. Together with their limitation to range 5 as well as Cassian and Iden as natural sniper hunters that could limit their ubiquitous somewhat. Or at least accelerate the Sniper Wars.
