First thing is first. How many points each rank takes is now outright told to you in the UI. This is a good thing.
Skill point gains, however, have dropped to something near a fifth of their old values. I never noticed it in alpha before, but looking over my photos it seems like the system has not changed. All those little messages that spam you after every strike about gaining proficiency, those get added up, and when you successfully kill a mob, awarded to you in a lump sum, perplexingly re-labeled as skill points.
Anyhow, what was coming in in bursts of up to 300 points per skill up proc, usually averaging 150, is now coming in in 30s and 70s, averaging about 50 points per proc. This means that instead of gaining some avg 800 points per fight, you are getting about 150. EXP however, has not changed, and thus your physical ranks level close to twice as fast as your skill ranks.
Alongside that change, physical bonus points have done the Jenny Craig also. Instead of 75/100 points and a scaling point cost to up stats, you get 4-6 points that increase an attribute at a 1:1 ratio. I tried reassigning my points once because I foolishly wasn't paying attention and put my points into Vit instead of Dex (AND confirming it), and it warned me there was a time limit on it. It however did not hassle me and allowed me to restat my points.
Now battle itself. The attack values don't seem to have changed much, but I have little less than an hour's observation in a field infested with other players. My capable deduction skills tell me that my Pugilist from Alpha was far more accurate in these low levels than my Pugilist in Beta. Either that or that seemingly bugged case where missing a punch could proc another chance at a punch really mitigated this point. Similarly, because of the stamina gauge change, each attack only generates about 250 TP instead of the previous 500.
Now, Pugilist-specific, Haymaker is 8x easier to use because of the design of the stamina bar. It's about half the cost in stamina as a regular strike, so you are practically guaranteed to be able to hit it once you evade. Likewise, the message for evade is much clearer now due to the floating combat text, which will flash an "Evade!" over you. Other notifiers include the skill name on the Stamina Bar going white instead of gray (unusable), and of course the newly filtered chat window. Dodge rate also seems to be base higher than it was in alpha. Haymaker's animation also got an update, and is no longer a yellow version of Concussive Blow. It's now more like a vertical cat swipe.
Also, Light Strike has a defense/evasion bonus attached to it. Using it once buffs you for like 8 seconds, and is nothing like the sliding dps<->tank system I was previously led to believe. In fact, the message that you could get in Alpha, under mysterious circumstances, about maximizing your defense stance has yet to appear for me in Beta.
Finally, the check system. I don't know why, but it was always the assumption that easier mobs gave less bonuses, and in alpha, this was true to various extents. It was most obvious in the amount of EXP rewarded, a small blue dot mob gave less exp than a medium light blue dot mob gave less than a medium yellow dot mob. I'm sure the same was true of the skill points, though I didn't make that observation, probably in the form of less proficiency skill up procs (though still for high values when it did).
In the last 30 minutes of today's test, I most certainly was making the same amount of skill points from both a small blue dot and a medium yellow dot; the difference in exp was about 150 (800 and 1000 respectively). Nothing near the drastic differences in alpha whereby a small blue gave something like 2-300 exp, and a yellow 1000.
My advice to others, is to stay on rats, at least up to skill rank 5/physical rank 8 as there is very little difference in risk/reward between rats and beetles. Beetles are actually more dangerous as half the beetle population are protected by Roselings, which by some act of cruelty are now closer together. I can't tell you how many people I watched die trying to nip a beetle between two Roselings. Chigoes actually hit for a sizable amount, and I couldn't find Colburans, probably because I stayed south of the camp as I didn't expect the skill rank to rise so slowly, and was trying to predict moving to aurelias and dodos near Cedarwood within an hour.
