Wraiths Ablitity improvements

I really like Wraith and her abilities but i feel like they lack a little bit. the passive ability is great but the tactical ability has a really short duration time which makes it hard to even reach cover i understand why it cant be too long because it would make it a bit overpowered so i think it would be a good idea to remove the trail on it so people cant just keep there sites on you when you are trying to run for cover or flanking, it will also give a bigger variety of plays you could pull off like going invisible getting behind the team and flanking or just getting away with out someone just following your trail and shooting you as soon as you are visible again, It defeats the purpose of it and if you keep the small duration time you wont be able to run too far away and you wont be able to flank all the way around a massive area you will have to use it wisely but if its is used wisely its really useful where with the trail is kind of useless unless you are surrounded by cover and if you are surrouned by cover what is the point of using the ability if you can just slide behind cover. if being completely invisible is too over powered then another good idea is to increase the speed of her movement while that tactical ability is active so she can at least reach cover or a better position with out someone trailing her and shooting her as soon as she is visible again. there has been so many times where i get caught out and try and use my tactical to get back to my team or a better position but im not moving fast enough so they just follow me with their guns already out and i have to wait for my character to pull her gun back out. because of this i havn't actually been using her tactical very often.
