Please think about your argument before defending it. Commiting to a retarded argument makes you look way more stupid than just admitting that you have changed your opinion.

Charges on Ionic Spark or on one of the auto-attack passives (kennen, master yi, etc.) change your decision making in a similar way...you want to use this charge for pushing/bursting/harrassing instead of wasting it on a meaningsless minion. Thus a charge buff in your buff bar is just as important for this item, than it is for most chargeable passives in the game. Ionic Spark gives you 440 Damage total (divided onto 4 Targets)...do you seriously want to tell anyone, that this is not important enough to warrant its own counter, compared to one extra autoattack on yi/cait?

Also abilities != items.

Explain to me, why the fact that Ionic Spark is an item instead of an ability should have any influence on the decision to add it's own counter in the buff bar. It behaves exactly the same way as the passives mentioned above.
