Question About Respec Slotting

Is it possible to reslot lowbie IOs during a respec at, say, level 50?

I've never tried this myself. I'm asking because I don't want to lose my level 30 Steadfast Protection KB and Res/+3% Def enhancements on my level 47 tank. (His slotting leaves much to desire, and I want to try and make him better once he hits 50.) I always assumed that you couldn't do this, but I believe I've seen a build on Mids' that had a level 20 IO on a power in the 40s. I'm afraid I'll lose the IOs, and I don't have my other build to rely on (though I know I'll have a third build when I unlock my Alpha anyways... I'd just prefer not to touch it quite yet).

Thanks!

You could reslot with all level 10 IOs if you wanted, not that you would want to. You just couldn't slot something that had gone red, like if you had left a level 10 TO in something.

It's the difference between Invention Enhancements and Single/Double/Training Enhancements. IOs never go bad.

I regularly slot level 33 IOs because I exemp so often.

Of course you can slot your lower level IOs, as long as you have a power that can take that set, otherwise some sets would be totally useless (like sets that max out at level 30 or lower for example.)

In fact, it is generally optimal to slot level 30 sets when possible, since those give good enhancement values, and you get to keep the set bonuses when exemped down as far as 27.

And some pieces, you want as low level as possible due to them not working more than 3 levels below their level. Others (like procs) don't matter the level since they work as long as the power is available.
