You ' re giving it 2 roles at the same time an antiEngineer rifle for taking out nests , and an antieveryone rifle for taking out players who have damage resistance , with two downsides tacked on that do very little to specialise the weapon . There ' s just a lot of problems there firstly , Engineers cannot give their team bullet resistance and he cannot gain it without a Medic ' s help , meaning the two roles don ' t synergise even slightly . Secondly , these two roles are useless to the Sniper no smart Engineer will set up in an area where the Sentry ' s range is easily exceeded and used against it , so Snipers dealing with Engineers is uncommon at the very most , and damage resistances very rarely appear , let alone pose a problem , so building a weapon around that isn ' t particularly powerful . If it was a weapon intended for dealing with Sentries with the resistanceignore applying to the Wrangler , I ' d understand more , but I still wouldn ' t see a use for it . Snipers and Engineers sit on the back of their bases , one shooting at the front line and the other preparing for the enemy to come to them .
