The only things that make this game good are the parts they took from btd6. Battles 2 is a shitshow, really. Whoever can send Fortified DDT's first basically always wins. Its just the same game on different maps. Since XP gain is so slow, you aren't going to try towers you don't have any tier 3 unlocks on. Battles 2 actively encourages never changing your towers and only doing what you've been doing for the past 40 matches.
