Alblaka has denied all all-in-one and combo armor suggestions i believe his words were something like "if you want stronger quantum armor then you should play in creative mode"
also repeating previously denied suggests is frowned upon here some annoyingly repeated suggestions can even get you banned (or at least flamed to the nether and back) please run a search to check if your next idea has been discussed before posting.
u can beleive me i searched suggestions section and HELP: Suggestion Compendium thread, didnt found any related information and started my own.
hmmm and fall damage reduced from quantum and nano boots not combo? ok, i see.
and i think its not a combo, just some sort of utility. Its really annoying to switch to electric jetpack to fall in deep pit, and then switch back to quantum suit quickly (to not to be overwhelmed by mobs)
