Well that's what my point is. we don't see much venomous so i can't make a comparison to that, but i'm 99% certain caltrops (or even EX caltrops) don't tick damage anywhere near as fast as the acid does. But stacked ticks is the point of the acid and I'm not saying to remove that.
I'm pretty much the authority on how Venomous' dots work, so I'll try and explain them real quick. First off, they're entirely different from Alien's. Each (standard) stack of Venom does 1.5% damage over 5 ticks and starts the ticking process in general. Each stack after the first does 1.5% damage + (n + .35%) bonus damage for each additional application, where n is the amount of bonus damage applied by the last stack. So it would look like .35 for the first, .35+.35 for the second, .70+.35 for the third, and so on. This leads to ridiculous damage if you can start a combo and apply many stacks, the weakness of Venomous being that you can't really do this from a 50/50. All of this damage is applied over the 5 second duration of the initial venom application. It also makes maximizing combo damage a pain in the ass, especially while factoring in that the dots scale to the combo they're in. If you have one measly little d1 tick going before you start a corner punish, you can lose 10% damage, easy. Here are the charts that were made off my figuring all this out

With Alien, when you hit 2 sprays, you've got 2 sprays. It's a flat increase like any other projectile. Get hit with Dark Beam twice, 16% damage done immediately. Get hit with the acid spray, 16% done over a course of however many seconds. There is effectively only one difference I can see and that is that Alien's projectiles are partially unscaled in combos. The initial hit likely is, but the dot itself? Not from what I've been told.
Also, as someone who read this thread, you came off as incredibly condescending to Omooba based off your own lack of clarity. You repeatedly stated you felt that the total damage was fine, but the duration was the problem. Then when you take the time to clarify that you mean the damage of the individual ticks, you do it by lowering the actual total damage of the spray. Why wouldn't he be confused when you are being so contradictory? Your entire argument is just...pointless, by the way. You seem very upset that the 8% projectile is eating away at your health over the course of seconds instead of instantaneously. If anything, that makes it weaker than a normal one when done outside of a combo.
