Here is the final proposal.

It is heavily based off of the community feedback, but Cat Merc's combination of Planetary Conquest meta review and thoughtful spreadsheet was exceptional. Thanks everyone, especially those that posed "this should be scanned by this" were very good for those last "yeah, that makes really good sense" tweaks.

Final Numbers

Here are a few collected guidelines from the community and CCP:

Design Principles
Lvl 5 precision Assault should scan lvl 5 scouts in close
Assault should scan undampened sentinels in long
Close Range should be long enough and strong enough to matter
Max prior range should be the same, reducing Amplier module
Max prior range should be the same, reducing Amplifier skill
To allow counterplay - precision modules give an equal penalty to profile
Not changing Scout base numbers at all; this round
One dampener should get Mediums some benefit
One precision should get Mediums some benefit
One amplifier should get Mediums some benefit
Lvl 5 Short Medium Precision should scan Prototype Equipment
3X dampening on Sentinel should get good benefit
No Directional Arrow on Minimap
Adding properly calculated EWAR stats to fittings screen
Commando should have better sig profile (-5) than Sentinel, Sentinel has better precision (+5) - skirmisher vs point defense
Assault should have better sig profile (-5) than Logi, Same Precision, Logi has better range
Sentinels need one Precision to scan down PRO Remote Explosives
Scouts are now only unscannable in Medium and Long Range

Standard Scanner scans Standard Equipment
Advanced Scanner scans Advanced Equipment
Prototype Scanner scans Prototype Equipment

For later discussion
Scouts get redefined with efficacy, possibly other attributes
Active Scanners
Vehicle Scanners
Uplinks with different Scan Precision
Size of Dot or intensity is based on profile, combined with precision penalty
Action influenced profile
passive bonus to cloak, higher when active, helps make it useful after "decloak delay"
Cross bonuses/penalties (range and precision,etc)
Range Amps to High
Extenders and/or Plates add signature profile
Special Spy Uplinks
Changes to Gallogi/Cloak and Focused Scanners go hand in hand

Well, the scout is naturally better at precision, so I don't see an issue with that at all. Why would the reverse make sense?

I do think dampening for medium frames needs a buff.

Can you provide specific examples of the best combo's of ehp/range, and precision...and what it would take to beat them from a few suits?

I would love to see range amps in high slots. and codebreakers!

I'd love to see no chevrons over enemies heads from passive scans...should be a minimap thing, not the actual screen...it's no damn dumb.

Yeah...as I've said elsewhere I've suggested that scan range be nerfed significantly.

2 complex plates is like 300 ehp + what 200 ehp base? 500 ehp is not a super high ehp suit. it's decent..and it's enough to slay, but it's not "high ehp"
