Nether Blade is why it's so strong.

When you do you burst, sometimes the opponent manages to nail you with his spells. The thing is, burst casters usually have relatively long cooldowns (4+ seconds) on their spells and the increased 15% MR means Kassa will survive; this means that during the time their spells are down, Kassa just gained maxed attacks speed and has an on-hit damage buff that scales with his magic penetration. Combine that with the fact that burst casters are usually squishy and they are essentially punished for bursting Kassa. Obviously, once the AS and W buff are finished, riftwalk is most likely available again for a quick escape/chase.

If you combine this with the rest of his kit, Kassa is a champ that delivers a powerful burst every 6-9 seconds with no retaliation possible, but should the opponent actually manage to somehow burst back he just left himself vulnerable to being DPSed like crazy with even more magic damage.
