Yikes! $250/year subscription for plug-ins? I have too many software subscriptions already...currently $2k/year.
I understand the appeal of subscription software, but unless you can make use of a large package of software, individual pricing makes more sense to most people. Adobe took a lot of heat when they introduced the Creative Cloud, and eventually started offering individual apps for subscription. I already subscribe to RedGiant's software, which includes a gaggle of PremierePro/After Effects effects plug-ins. Many of the effects from Motion Array are redundant, so it doesn't appeal to me.
