Regardless of weapon teams, Rifle Nades are just a really poorly designed mechanic. They don't clear garrisons properly, which is what they're supposed to do, instead they result in gimmicky, effortless squad wipes.
Firing a Rifle nade over a shot blocker that you literally can not see coming and have no time to dodge because it's instant detonate resulting in a squad wipe is just silly. It also makes no sense how they detonate instantly, combined with the fact they have the best animation that can be very hard to spot compared to other grenade animations. It also breaks late game and makes LMG Grens far stronger than what they should be, because it makes other long range LMG unable to remain static for fear of being instawiped. This encourages blobbing because you can't risk fighting on multiple fronts against Rifle Nades.
Giving Grenadiers regular grenades like Volks or Fusileers would be a great chance to not only increase the viability of allied support teams, but also just to decrease the skilless "free" squad wipes and result in more tactical play. It would also help Ost clearing garrisons which is something they lack.
Panzer Tactician is such a no brainer no skill instapop escape tool. It also breaking button is stupid. It should either have an activation delay (like with USF vehicle crew evacuate) so it has to be used pre emptively, or it should be an aim launcher like the Sherman that takes time and tactical placement.
Or alternatively it just shouldn't be on Panthers and Tigers, the massive Health and armour on those vehicles is already more than enough for them to be incredibly difficult to destroy, especially combined with the really low rate of fire of Ziss Guns.
With the abundance of RNG, especially within tank battles Coh2 really needs to increase the skill differentiators by removing abilities and tactics that require no effort or skill, as well as preventing a player from being punished if they make a mistake and get outplayed. Panzer Tactician is one of the worst offenders.
