After seeing my shellder had the skill link ability i decided to go to the pokemon forums to find out what it did... "Skill Link enables multi-strike moves that hit 2-5 times per use to always strike five times." After seeing this i decided to do some testing in game and realized that the amount of times my move hit (icicle spear) was still random... please fix! ;D Pokemon forum post: http://bulbapedia.bulbagarden.net/wiki/Skill_Link_(Ability)#Effect
Yes, some abilities and moves are bugged. Thx for reporting this and it will hopefully be fixed soon.
We have someone working on Ability's and Move's as we speak. Most if not all should be fixed in upcoming updates
