I am glad to see some new omnis. With the rought after the civil war followed by the post jihad proliferation of handheld weapons, I was afraid they were killing IS omnis.
Omnis are my personal preference for logistics reasons (frankly, with the existence of omnis, it's hard to justify the existence of certain designs) and also since I run combined arms so they mesh well with BA (also nice to see a couple more heavy BA to carry around). I am especially intrigued by the Gun being that it's specifically designed as a rear line unit despite the omni markup, and I am also glad to see we finally have an Omni hover designed for combat rather than as a bus (and again, with BA, the combat hover can fufil that role somewhat, though it is a mite slower). I am still waiting to see VTOL and WiGE omnis, though.
After seeing what the RotS did with the Bolla (redid this WoB omni to support IS infantry formations and swapped the C3I for a C3S), I am really hoping the Celestials get the same treatment.
I should mention, though, I don't really see how the new Templar improves much on the old one.
