-Make Lp sellable/contractable on the market
-remove timesink missions for datacore agents and replace them with something that actually makes people want to do them (ie sufficient reward for the time actively invested - unlike the current system
-allow people to respec skillpoints if they feel you've nerfed the everliving #$%^ out of the entire datacore skillset and they just want to get their considerable time investment back.

Edit: some form of decrypter for LP exchange wouldn't be a bad idea either.

LP or RP in contracts?, if RP then +1

LP on the market .. best not. What little lore Eve has left would be lost if it was to be done, don't want people such as my self who are -10 with a couple of Empire suddenly turning up in their naval loyalty stores to buy stuff ..
RP on the market .. automatically generated, aka. free stuff, being sold off .. ugh. Best not.

Refurbish SP .. err, no. We go over this every damn time something changes (ECM, Nanos, Neuts, Rats, SCs, etc.) and the choice to exploit a certain aspect of Eve was yours and yours alone. What you should be asking for is for CCP to look at other ways in which the now less useful skillset can be made 'worthwhile' ... such as:

Timesink R&D mission: There have been rumours of :insert pirate faction: doing their own research in the XYZ constellation. Help me get what documents they have to facilitate my research and you can keep whatever else you find.
- Probe constellation in question until site is found. Requires hacking, salvaging and combat to complete with possibility of datacores galore drops as well as an assortment of invention materials (basically a 'targeted' exploration task).
