Anyone feels that it is much easier to spot CELL cloaked players during multiplayer or it is just me?

Depends on the Map really. I've found on Maps such as Terminal CELL are easier to spot, but on Maps such as SkyLine MARINES are easier to spot.
I use the Visor enhance and it negates the cloak effect if I look at them through a scope. Its great at spotting cloaked players at long range.

I actually agree that for the most part the colour of CELL players makes them slightly easier to spot than Marines; although there are areas where Marines are easier to spot.

Visor enhance though is just pure LOL for snipers. I usually try not to run out in the open even if I'm cloaked, but some people don't seem to grasp that they're NOT actually invisible, and so often get shot by people using that perk.

Oh so i wasnt wrong, kind of remind me like the predators cloaking system. You can actually spot them if u look close enough =)
