I changed a bit my mind about this. All Tier 3 Inspirations are not equal. Robust sounds really better than Courageous that doesn't upgrade that much compared to Tier 2 Resolve
Finally, I changed Robust from Greater Lay on Hand to 10s. This isn't exactly twice the effect of Lay on Hand due to initial tick and worse PL scaling (Greater Lay on Hand is a Tier III ability), but I think it's good enough considering Robust also comes with AR and CON buff.
Hands of Light is buffed to 15s. It might not be as universally useful, but still good enough if you want to prevent a frontliner from being interrupted. It is still the only ability of the game that does this.
Apart for this, I didn't make much changes, but I had to take time to clean up what I previously did. The Mod files are now much lighter, in order to avoid conflict with other mods. I also corrected the description, but in english only... I don't plan to make a multi-languages mod for the moment. Even if I do, I can only do it for French, Spanish, Polish and Russian by my own means.
I had to re-test everything, so I think I will avoid dirty programming next time. It ultimately costs time ! BalancePolishingModBuffs.zip
