1.: pretty cool, but the dmg-cd is a little to long (maybe 5 and 3 (with summoners insight)), else harass lanes will become way to strong

2.: seems rationally acceptable, low price but the item isnt too strong either (same stats as flash)

3.: **exhaust reduces the dmg of AA not the AS** everythin seems ok, but SW gives 1 entire sec bonus which is a little too much for a mastery at the bottom of the tree (either 0.5 sec bonus or reduce the slow to 25%)

4.: exhaust leaks the dmg reduction...which is quite bad considering exhaust as counterspell to adc lategame, but now it is a very strong antiescape...... mhmmmmm... im not sure

5.:imo the best solution, but kind of unfair towards those champs, who have no hardcc, and even then most spells need more then 0.5 secs to arrive (taric stun, skillshots...), so maybe change it to the mechanic of recall:

if u take dmg during the 0.5 (maybe shorten it to 0.4 sec) u will not flash, but the spell doesnt go on cd anyway (just like recall with lower channelduration and range)
