Bigger form more rubberband?

Hi, I'm looking into buying some tonics lately, and I do a lot of stuff like UW/FoW. I am currently using a mad king tonic, which is relatively tiny (the form). If I were to buy a tonic with a big form, like Kuunavang or a Flame Sentinel, would the chance to rubberband (collission) increase? seeing that my form is bigger. Or is it the same for every form in GW, but will the protruding parts just be ''static''. Thanks in advance.

You have to distinquish your looks from your real form. This isn't real life, this is a game with other forms of physics. Your true form is a very rudimentary cilindric form wich is actual invisable. The size of this form is the same for everyone. Class, tonic etc doesn't have anything to do with it. This is your real (invisable) size and what causes things like collision or rubberbanding. The way you look is projected over that form, where the center of your looks, is also the center of your real form. So when you have the form of a tiny monk, you prolly have an invisable barrier around you, while in the form of kuunavang your wings will magical goes through walls, cause the wings aren't actually there.

Or to answer you shorter, no, tonics doesn't increase rubberbanding.

i have a kunnie, and it doesnt cause ruberbanding or increase obsticle stops. it does however, at times, obscure the view when in mission/explorables.

that is very true off course, the size doesn't matter, but is blocking view.
