This idea got tossed around earlier today in our guild mumble. But the idea of a Blast network style bomb for use as PVE/PVP (lockdown) would be a fun idea. No explosive radius in the form of a circle, but an extended cross as it exists in blast network. I'm not sure to the actual length as to make it a viable choice but the novelty of it is appealing. It already essentially exists but the main theme would be an increasing distance reached as you go up in star value. I'm not sure as to how difficult it would be to actually test and bring this over for personal use but a secondary feature could be that it allows the player to use an explosive weapon that features their color scheme.
The implicated use of the bomb in Lockdown could be for strategic holding of choke points that are narrow and clearly defined. It would lose a lot of use in wider spaces and as such might be a fairly balanced weapon choice.
We've already seen the explosion style used in Blast Network and the hammer charge attack of Warmaster Seerus (this shows that already the framework for the animation exists and can be used in a pve scenario). It wouldn't be a far stretch of the imagination to see it being used by knights in the future.
Any comments, additions or constructive criticism would be greatly appreciated.
Two words: Crystal Bomb.
Seriously though, I'm not really seeing the advantage that the implementation of a PvE BN bomb would have over the existing Crystal line.
