It's not too easy. For a ---decent--- win rate, you need a partially upped deck, or rares, or both. I've spent plenty of time working on the perfect unupped ai5 deck, and although many newbies love it, its only because it gives them a better chance. The games are long, requires great knowledge of the possibility of cards that could be played, and requires way too much strategy. I would honestly prefer FG's with one of the mostly unupped decks because although score suffers more, the electrum output is higher. The only time I fight level 5s is when I want to work on my score while still having a chance of winning good cards. You shouldnt need a mostly upped deck to have consistent win rates against ai5's, and if you do, then the deserve a reward worthy of using upped cards. Dont get me wrong, I find them easy enough with a deck engineered specifically for them that is bogged down with a combination of stalls and cards for every situation and games that take forever, I just think thats a ridiculous requirement for the reward is all. What would be the solution? Make them harder AND increase the rewards, or make them easier and leave the rewards the same. Either one of those situations would work, however, how it is right now, wont.
