@Yoga I have already addressed and repeatedly agreed that there should be something done to balance the No-Stamming on both sides. I even noted this in the FAQ just to avoid these types of posts. The Developers have been trending away from the No-Stamming very causally over the last few updates. We can't solo at all on the new Insane Campaigns, they reduced the trophies for normal (the no-stamming spot for many) etc.
I do want to point out that this could be an overpowered unit when the No-Stamming eventually grows old and broken. Proletariat knows full well about the Timber Beasts, and they said they are talking about it. Consider this post me finding a small lump on my back, and reporting it to the doctors just in case it turns out to be something malevolent.
Plus, you must consider PVP. If 18 Punks (6 x 3) gets thrown out in four waves, this makes PVP almost impossible for us Survivors. I see this as a glimpse into what the future, not the present, may hold. If a unit (at level 20) can kill three tanks nearly ten levels higher than the Punks, then something needs to be done before team gameplay if fully enforced.
I'm absolutely fine with Infected getting some solid updates. I just see this one as a little overpowered, and I thought there was no harm in bringing this possibility to the Developer's attention.
P.S. Farming is so outdated...
