Me and Bioshift did all maps legend duo with two-hand swords and put together a playlist, if anyones interested in seeing how two-handed swords play.
Bio also did a nice writeup of our thoughts on two-handed swords in general:
The most glaring weakness of Saltzspyre and Kruber’s 2h swords is their inability to effectively deal with armoured elites mixed with hordes. Contrary to popular opinion, they are acceptable at DPSing through armour, while being possibly the strongest weapons in the game at safely massacring hordes. However, armour in the mix does throw a spanner in the works.
Over the course of our 13 map expedition, we adapted a strategy to combat this enormous weakness. Incoming hordes will draw all ambient elites and trash with them straight to you, so the answer was to simply be proactive in eliminating every elite in any given area before the horde horn was called. This hyper-aggression was very possible with double 2h swords, since it only takes a few moments to focus down Warriors or Maulers, and a single person can juggle 2-3 Stormvermin at any given time, since the stagger is so strong on the weapon.
Understanding our weakness meant that when we were unable to clear all the elites before the horde reached us, we were more liberal in the use of our resources. We became very efficient at expending bombs or chugging potions to deal with elites + hordes in bad places, when it might not be immediately clear that it would be necessary. We also became more liberal with exhausting ammunition to quickly soften elite ambients before they reached us during or before a horde.
The boss damage of 2h swords is very underrated. Dealing around 25 damage per charged swing is much more efficient boss DPS than a lot of melee weapons. The problems start when mobility is required, i.e, against Chaos Spawns. They are also not so terrific against super-armoured lords such as Skarrik and Bodvarr.
