Ok, here is my feedback: The borders are more secure than realistic. Simply put, someone will flee with the disease across borders that are closed under pandemic situations. Panic, human nature, whatever you call it.
Second, the game is fun outside of it really being about a few selections. However, Madagascar could use an airport that actually gets planes. There is an airport there, and it would make it a little bit less of an issue.
RMcd makes a good comment, but you can do the same with the highest rank of healer or warlock, if you have patience. Also, for those wanting to power up faster: Get max ranks in your personal damage first, then a few armor and health. Once you have 2 upgrades of armor and health you can just solo everything until you can make an archer at max level (and save some gold)... up to the last battle. Once you are level 15, you can get the map-wide aoe. At this point you can stock levels as follows: Select a max near but not at the end of the game, as this will maximize your exp earned; add as many first rank mages as you can; use the aoe and let anything that stays up kill mages (use your first spell to hit them if they are about to die (leveling it up is a good idea, it is better after a couple ranks in your aoe due to it hurting the boss. Only fire should ignore it, as the fire aoe does more boss damage anyway). Continue until you have leveled as much as you want to.
Here's the easy super leveling method: Get dark from, double slash and boost, and upgrade your weapon as much as you can. Then enter the tournament. Use dark form, and use boost. Next, use double slash. Now, continue using the repeat last cast option. Note that mana and hp refreshes each round in tournament, but your buffs do not. Now you can just grind levels until 1.75 X your damage (at which point you stop, buff your sword and whatever else, and can repeat again).
