Not really, no.
Shatter seems more PVE oriented than Seal Rock and the only way to get into actual PVP in that mode is to branch off and look for isolated nodes and hope you meet resistance, which is risky even then because you have a good chance of getting ganked.
Frontlines needs to include things that make objective based game modes in other multiplayer games great.
Like a Kill Feed that stays relevant to your team (who your team kills and who killed your teammates), sort of like in the Feast.
Supposedly Secure is a good PVP mode, in which case they need to bring the level cap on the ARR modes up to 60, or at least create separate instances.
What I really want to see however are modes similar to Runescape's PVP, like an FFA arena you can enter, or WoW's impromptu dueling feature.
