i agree on this.
Thats how it was. and how it should be.
If there's a lace nearby, u cant activate it.
If you activated ur ultimate BEFORe and THEN a lace guy showed up, they shouldn't be able to slice through ur shield like a hot knife through butter...
The ultimate duration isn't long, so this ladder senario will leave the guy with at most a couple seconds of invulnerability.
Whereas the current ultimate is almost useless considering that a lace is almost a staple item for every player in the server....
