Just noticed that Cloaking Device for SOA unslotted is giving out a value of 7.5%
7.5%... Defense?
The info tab for the power under defense says 3.75% ( self)
That should be correct. As Aggelakis pointed out, 3.75% is unsuppressed, 3.75% is suppressed.
Does SOA Cloaking Device just give higher numbers then the Blasters Cloaking Device from the Device set or is it a bug ?
Cloaking Device for Blasters should be 1.75% Defense unsuppressed, 1.75% suppressed.
On the surface, it would seem that the Arachnos Soldier power is approximately 122% stronger than the Blaster power. (3.75/1.75 = ~1.2244)
But that's not the whole story.
The Defense self buff modifier for Blasters is 0.070. At a modified base value of 1.75% buff for each component of Cloaking Device, that means the power has a base value of 25% Defense for each component. (25% * 0.070 = 1.75%)
The Defense self buff modifier for Arachnos Soldiers is 0.100. At a modified base value of 3.75% for each component, that means the power has a base value of 37.5% Defense for each component. (37.5% * 0.100 = 3.75%)
So, yes, the Arachnos Soldier Cloaking Device does have a higher Defense buff than the Blaster Cloaking Device. It is, in fact, 150% stronger than the Blaster power. (37.5/25 = 1.5)
Is it a bug? I haven't heard anyone officially state that it is or is not, so I can't really judge.
