On another note: Does DE have something like a donation option? I'd give them a bit of my money if that would allow them to rethink the server-side vs client-side problem. Seriously, it shouldn't be a problem to get a slot these days. That is the value of a maxed 'rare' (I guess we'd need terms like super rare or ultra rare in relation to the really common rare mods) or four to five T3 keys.
Now that you can trade for Platinum, is there really room for this request? A warframe slot costs 20 Platinum. With 50% discount the prices become reasonable with 75% as a very nice bonus to get Platinum for cheap.
The only thing you could argue with is the horrible exchange value if you do not apply a discount. That said, the developers need to have some income and slots are probably the main reason (besides Founder/Prime Access) for buying Platinum in the first place. Warframe is F2P with a shop focussing on cosmetics rather than game breaking weapons or armor.
