A while ago I noticed something strange when I was in a group with a Guardian Fighter or someone with the Wheel of Elements Artifact. Sometimes Into the Fray or the Fire Buff from the artifact would disappear randomly, so I decided to take a closer look. The next few runs I observed the Buff-bar of my group members when the Guardian Fighter was casting Into the Fray. Everybody but me was keeping it for the whole duration. I joined another group with 3 TRs and voilà, the other Rogues lost Intro the Fray randomly as well. It appears that Trickster Rogue's can deflect some buffs. The only thing that distinguishes TRs from other classes is the higher deflection severity, so I think it's most likely a bug with the deflection severity.
Buffs affected from this Bug that I know of:
Into the Fray
Wheel of Elements: Fire
Here is a short video with the bug in action.

Some STO damaging abilities (Tachyon Beam) are coded as negative heals for some reason.
Maybe in Neverwinter some buffs are considered negative debuffs, and therefore are triggering the evasions?
This reminds me of conflict that was fixed some time ago - DC feat:"Cleanse" and OP temporary HP - the HP was seen by Cleanse as debuff and removed it.
And now: Into the fray - gives temp HP
Wheel of elements - the fire itself doesnt give temp HP, but Wheel as a whole has an option of temp HP buff.
Perhaps this is root of the problem - temp HP is a "negative effect" from game point of view.
