Since the rifle grenade plays as an ability which goes along with the strengths of the grenadier.(Long-range combat) I've played plenty of games where I am up against Ostheer players.
I have two options which may lessen the odds of squad gibbing.
1. Closing the distance. This is my safer option since it deny's the ability to be used while going against the strengths of the grenadiers.
2. Squad formation. Remember how you can reface tanks, well this also applies to infantry as well. Unless you are making a formation near cover, this option can allow the models to spread out unless they're right next to their cover. This lessens the rifle grenade's power since the models were refaced and spread out of their cluster formations. This may not work well if the unit on the receiving end happens to have low health or in negative cover.
I don't see why this thread is needed in the Balance section. This is more of a learn to play issue. After playing plenty of games against the Ostheer, along with mistakes, rifle grenades are expected to be used by the Ostheer at some point. To disregard this priority when facing grenadiers is the reason why it would seem that it is a cheap ability.
Does it need some tweaking? Yes, maybe the ability should have a lower range when grenadiers are suppressed?
