Just jumping in, on this one.
When the Tacky potion (snare-pot) was getting thrown around for any little advantage some years back there was a bug with it, where the snare would persist and one destro guild noticed this. Their wording afterwards when reporting it was something along the lines of "it felt like we were back on lvl 16mounts"
So I would say that a constant 20% snare reduction that is not only blocking most clensing, because of the constant reapplication, will make it just that tad bit harder to manuver outside of the frontal spray from Mara channel, away from a choppapull, or just outside the killone of a warband. 20% matters. is it the end of the world, no absolutely not.
The fake complaints come with anything that gets you killed when you lose control over your character and your choices to survive feels against you(I shouldnt had died there, i was safe! I played perfectly) feels more unfair, if you get pulled and die, if you are snared and thought you could get away and then die. if you just barely escaped death and get sucked right into the grind.
The snare is probably just fine, its just annoying and break the illusion of being safe imo and ever so slightly makes you play more predicting gameplay and try to guess where the killzone is within the next second instead of reacting to where it is right now.
And Flame potions and Tacky pots are disabled.
