I guess everyone has their own opinion about this, but for me I find it bad form to use. At a certain point it defeats the purpose of sbh, and from what ive seen since this post has been started, more and more people are abusing it. Whats fun about getting spotted by an apc miles away? Defeats the purpose of spys too. GDI has its advantages just like NOD, leaving them at an equilibrium, but with the abuse of this id say advantage is with GDI now; nod cant do anything about gdi's higher hp and firepower, but now gdi can spot stealth units from a mile away.
Sure if someone notices their retina turn off randomly and think it might be an sbh, thats cool. But someone actively waiting at the back of gdi ref on complex and abusing this glitch for 2-3 hours is just wrong.
Imagine renegade where every player knows how to do this, sbh will be completely obsolete. Its not the same as 1 man wall hops because it can be avoided by simply not doing it, and since both teams can do it, I find that comparison irrelevant. Theres no glitch nod can use which makes a gdi unit completely useless....
Just how invising was banned cuz it makes the game impossible and ruins the fun and point of the game, id say this is the same concept.
