The MR13 Kuva Drakgoon is a massive upgrade over the base Drakgoon, with good Crit and high Status Chance. With one of the best stat distributions of any Shotgun in the game, it is a little unorthodox, but is quite powerful and a surprising amount of fun.
The Secura Dual Cestra is one of my favourite secondaries, mainly because I love blasting walls of neon lasers everywhere. Unfortunately, its drawbacks coupled with Secondary mandatory mods meant that I was previously never able to have it user-friendly, as well as fully effective. The implementation of Melee 3.0 (well, 2.9 implemented the important change), coupled with the Weapon Exilus slot allowed me to finally (somewhat) realise my dream of an effective and user-friendly Secura Dual Cestra.
