This new arena is, as I see it, a mixed bag. There are some things that I was VERY pleased to see, but then on the other hand there were some things that disappointed me. The following is my attempt to lay out both the good and the bad without getting as emotional as... say... I was immediately after each and every match. *cough* Sorry to everyone who had to see that in-game, by the way...
the Good:
Crown entry fee. Very inexpensive crown entry fee! A player could spend their mist energy dungeoning up some crowns and with what they earn there they could spend all evening in the arena and not run out of cash.
Token distribution: This surprised me the most, and the most pleasantly. I LOVE that participating in the match to its end always gives you a krogmo coin even if you lose, and that winning only gives you an additional one (plus some kind of bonus? I don't even know. We activate the bonus every time but I have yet to win it myself). This means that as long as a person keeps playing, they can earn the prizes only a little slower than the people actually managing to win.
Prizes mostly being recipes. They can be sold, they can be used to craft unbound 3* equipment that can then be sold (or given to friends), even right now on the first day these items appear to usually run something like 25000 at the auction (compared to about 15000 for normal 3* gear). It is good to see that we won't have to buy pre-made, bind-on-acquire weapons like the other token rewards to date. If a person doesn't care for the arena they can still reasonably acquire the new stuff, as opposed to having to run the same boss over and over until they're completely sick of it. I mean, I want some quicksilver gear but I've already done Roarmulus SO many times just to get two of the weapons, I just.. I don't like doing the same thing over and over again. So yeah...
the Bad:
People will spawn right next to you. They are invincible for quite a while after this happens, but they are IMMEDIATELY able to plant a bomb. This means that you will be taking cover from a bomb, only to have someone appear right next to you and immediately get to kill you for free while they remain immune to their own bomb, your bombs, and whatever bombs you were hiding from at the time. This is incredibly frustrating.
Poor hit detection. It's not even an issue of lag (though people have told me that's an issue too). I can be fully behind cover, not moving, and still get killed by a blast going through the adjacent square. I'm sorry, but bomberman styled games only work if you only get killed by the attacks that actually HIT you.
Can we walk through the bombs? Can we not? There is no consistency in this. Sometimes we get trapped on the bombs, sometimes we walk right through them. This needs to be a lot more consistent for this to work at all.
Lack of Strategic/Special power-ups. It's just a little boring and predictable (apart from the things that aren't working consistently) when the only power ups are speed, bomb count, and bomb power. What made Bomberman really fun was that one person would pick up a bomb-kicking or throwing power up, or be inflicted with the diarrhea curse, or short fuses. Without that sort of game-changing power ups, it's just cut-and-dry plant bombs at open spaces in rows and then hide, over and over.
I think that other than the power ups, the three other things NEED to be fixed. Better power ups would be a secondary thing. I agree with you completely though. Sometimes I die when I'm even a tile away from a bomb blast and then... dead. You can't walk through bombs, but they need to make that better too. I hate when someone escapes a bomb, and then when I'm trapped I really am trapped. I've only had people spawn next to me at the beginning of the match, but what happens is, we both die because we both place bombs to get out at two different spots, and trap ourselves. Even so, the pros are much more significant than the cons, even now. Knowing that it can get better with easy fixes is great (Hopefully OOO fixes some of those things).
