Shuumatsu no Izetta and Owari no Seraph are interesting shows about two sides battling against each other. Shuumatsu no Izetta mainly uses magic and not everyone fights, while in Owari no Seraph they use weapons to fight. Both of the main characters were motivated by a friend who they deeply care about, and there are homosexual undertones in both series (yuri for Shuumatsu no Izetta and yaoi for Owari no Seraph). Both contain a bit of comedy as well despite not having the genre listed, so it won't be exceptionally boring.
