Do You Thing Ivy Is Cheap
The only way she can really be regarded as cheap is when your dealing with low level players or even intermediate. This game has little sympathy for mistakes made and generally throwing the wrong move can lead to a 3rd of your health bar being ripped away. So most noob to intermediate players deal with up close combat and with both players generally in weapons length for both people at all times, it gives decent chance for the lesser player to fluke out...not Ivy however. Her whip stance (generally her worse among the 3 main) destroys noobs.
Ever spammed WP 6B+K2_8 over and over again? you'll either take away most their life or put them in critical finish range before they figure away around it. Where a good player will fall for it no more than twice and then rip you a new one on the slow recovery. CH 1A(B+K), 236BB will dominate almost all run ins. And if they get close good ol 4A+B, B to send them right back out of range.
With ivy in whip most players will never be able to get close enough to land a lucky hit. As well Ivy has ridiculous combos. However her most absurd ones are shakable...look at the one in my sig (her biggest combo)...most good players will escape both shakable parts but a n00b will be eating 125+ damage every time. If you don't know hot to shake, Ivy has some insanely over powered combos.
Next...214B...the noob killer. This move alone will wreck 90% of all average players and below. CL 214, CH K, K, A+B = major damage for a noob who will more than likely try to rise quick and block (also major RO potential!). Also most noobs completely eat it when you throw CL A+BA+K, 66A+B, 3...then again so do most good players.
Even sword mode can wreck them...22K, 214K and 6, 3B, 4K and 1KB(K) are completely spammable
However at the end of the day, when it comes to advanced play, she's good but has to dumb her move list down quite a bit and leave the fancy stuff behind (though SW 6, iCS is still hawt).
