Guild Wars 2

For PvE I would switch Rifled Barrels to a more useful trait (e.g. Precise Sights) as longer range usually only means that your target needs a fraction of a second longer to reach you. I would only use it for special targets like bosses when you need it to keep out of its range.

I have the same issue. Sometimes it seems to work, but not always.
I wanted to use this with the Med Kit whose tool-belt skill would heal for over 25% which in combination with Inertial Converter would lead to an always available heal when health is below 25%, basically making me only defeatable by burst damage >25% max health.
But as long as Inertial Converter does not work reliable all the time, it just gives an additional available heal every now and then, which is not really great…
