On the issue of remodding a piece of gear. When I level alts I typically go through 5 or 6 sets of custom gear until I find the one I like. While very doable with low level modifications, it can get quite expensive to accomplish at level 50 when you have Campaign pieces that drain the bank when you want to switch the mods out.
Solution: Allow the transfer of mods to a new piece of gear at the cost of destroying the old piece (and the old mods).
Or: Reduce the cost of removing mods at mod stations.
LOFTY IDEA
Custom Companions. Why not add a new companion that can be customized by the player? To cut down on data, they could be confined to several options, while allowing species customization, class options (maybe even choose their abilities and add a small skill tree), gift appreciation (limited to 1 Favorite, 2 Really likes, etc.), Some basic social options (such as LS, DS, Likes killing people, hates bullies, etc.), and Gear Type (restrictions such as: No healers with strength or tanks with cunning could take place).
This would certainly fill the niche some people are complaining about what with not having any force using healers, or not having that ONE type of gear requirement. Of course this isn't exactly a paper cut, more like a hemorrhoid (treatable but not necessary), but I felt it was something that could be a drastic improvement to the game. Maybe add a small story line such as: The Hero busts a slave trading operation, but one prisoner (the custom companion) is causing trouble with the other freed slaves as they are shipped off-world to be ingratiated into society. The Hero is sent to investigate, and the companion (ever grateful for being freed) agrees to stick with the hero after a customization process.
Of course, that is just one option for a story, and the appearance option could be limited to 5 or 6 presets to reduce data consumption (think, it would be like the population of the game doubling in a matter of days if they were fully customizable. Imagine that lag....)
Obviously a very lofty idea, but I hope someone open to suggestions sees this and passes it along. I'm still with ya Bioware, we haven't lost hope.
