As of late...
This will only serve to make Infantry Sections even more reliant on Bolster to be effective.
My least favourite thing about the Brits (my favourite faction) is that everything about Infantry Sections revolves around the fact that you can upgrade them at any time from an ineffective squad with less utility than Grenadiers to a very durable and dangerous mainline squad.
I've experimented this whole patch with never using Bolster but it just handicaps you severely and my wins have suffered greatly for it. I hate the way it's designed, but if the balance team or Relic is not willing to change Bolster then the British and Infantry Sections will never adequately be balanced.
