Quite the opposite - ADK and CDK only need 3 mil exp to max, sure...but the gains from maxing out a god or godbased team (hindu/greek/norse) are far greater, since all of the stats get multiplied, rather than just attack. My green team ran a train through two heroes, both ancient dragons (fire/water) on legendary with 0 hiccups. It farms almost all dungeons and has 0 risk. I can use it to farm masks, dublits, rainbow keeper etc within minutes and not have to worry about using beginner type strats such as resolve or poison. The only dungeons that will give me a problem are: Zeus/Goemon/Valkyrie/Hera-Is type dungeons that typically require an egyptian or zeus based team to defeat. It may look daunting, but leveling a team is really simple once you get the hang of it.
I guess this begs the question of what team I should focus on now. My current strat is giving on-color XP to monsters I'm going to use, but since I don't really have the components for a blue/green team I was going to funnel my blue/green XP into my red team, which most are around lvl 50. To be specific, I have:
Leader: Max noel//69 Grand Firedragon Tyrranos
54 Homura
39 Gigas max skill
44 Ardbeg
39 Echidna
With a friend Shiva I've been able to farm Legendary Water Whiskey, and did the same for Fire Whiskey, although fire took longer due to 10mil hp -_-.
I also have a fledgling dark team.
Leader: 44 Hell Queen Persephone
Rainbow Keeper
29 Vamp Lord
1 Dark Dragon Knight
1 Dark Dragon Knight
As you can see, it's probably too weak to field anywhere right now. I guess I'm asking if you guys think the potential of the dark team is better than my red team, and enough to warrant a change in priorities.
For those curious about my leveling priorities, for my red team the current plan is: lvl 70 Gigas -> 500k xp into Ardbeg -> Max Firedragon -> Max Homura -> Max Ardbeg. Not sure if I want to leave Gigas unevolved or not. I probably have enough HP and I'm hesitant about taking a RCV loss on a team that's already pretty low in RCV. At this point also, Echidna's super low stat growth is really unappealing so I'd jump focus for sure to another team.
For the dark team, likely it'll be as such: Get both DDKs to 70->get Vamp to 70-> Evolve duke and level to ~40 -> Evolve CDKs and level each to ~40 -> Max Persephone -> Max CDKs -> Max Vamp
