There may be other issues with the infiltrator in regards to weapons, certs, etc. (although in my opinion these are somewhat trivial) that need a second look, but I think many will agree that first and foremost the current cloaking system needs some attention. I know the devs have a lot of other issues to deal with at the moment, but if enough players create awareness for how frustratingly useless cloaking is for anything outside of sniping, then perhaps they will be willing to give it a second look when the time comes.
