Hm, the point of "freemium" products is always to make you want to spend cash by making you feel like you're missing out on something if you don't have .

Pragmatically speaking, you don't "need" 3 different cards (I assume you mean bot, alt, gun) per character. You  only really "need" two cards - bot and alt to MTM. MTMing a bot provides the greatest boost to combat prowess - it roughly quadruples the combat power of a maxed (but not MTMed) card. In contrast, the matching weapon upgrades combat prowess by maybe 20-30%. It's still palpable, to be sure, but you can do almost as well with a well-paired spare weapon (usually the powerful ones you get at 2m points in events serve quite well).

Certainly, it would be nice to be able to trade rubies for weapons, but I'm just saying that unless you've got Collector's OCD (this IS Transformers, so it's not uncommon), you don't really need matching weapons to drastically improve your team's combat strength.
