I'm not necessarily opposed to using 15.04, I've just always stuck with the LTS releases for deployment.

I'm the opposite. Due to stability and patch issues, I would never use LTS for production (only in a lab) except for the time when the LTS release is also the current release. Remember LTS is only a name and does not imply any additional support. Staying on old, out of date, unsupported OS versions is especially bad in production.
