I dont really understand the complaint in this case. While yes, enhancing PEN (or higher) is at times excruciating, the event kinda... doesnt relate at all. For one, the upgrade method is entirely different, with lower chances but no downgrade, and no repair costs. Secondly, only one person per region needs to get the pen for everyone else to get the rewards for DUO and up, as long as they reach PRI. Since both EU and NA got a PEN in the region during the first week already, these extra light auras are for those of us who are perma afkers and too lazy to grind (aka me) who havent yet managed to enhance their sword to PRI (though dedicated fishing is enough to bring you to PRI already in most cases during the event period). So instead of a "oh no, enhancing PEN was too difficult for our players, we got to give them more chances", the line of thought by PA in this case was more "lets give everyone the good rewards as well, even if they were unlucky in enhancing so far".

Again.. not arguing that enhancing isnt straight up evil and soulsucking at times, but the extra auras arent because of the PENs

Not buying it.  Currently at PRI with Tarnished sword and attempting DUO.  Burned through 240 Auras trying.  My stack is at 12 and it would not suprise me if I only hit DUO because my stack hits the guarntee DUO at 50.  That's potentially burning through a 1000 auras; who in the hell can grind a 1000 Auras?  Its why they introduced this event.  Bottom line, the 10% success rate from  PRI to DUO don't mean sh!t, because a 10% success rate is a 1 in 10 chance meaning at most its should cost someone about 200 Auras from PRI to DUO (20 Auras x 10 attempts).  RNG is so f'd up in this game.

So, because there is such a dismal failure rate for hitting PEN on tarnished sword, PA introduces a "catch up event" that gives extra Event Light Auras (100/day) just for logging in.  

Same as how bad hitting PEN is in general, so they introduce Ancient Anvil.

Same with new players not having PEN who faces a long slog before ever getting one when the new FG weapons hit this fall.  So they give a free one to everyone.

Sad.

Just hit TET with pity after 50 hits.... PEN is worse 2% and another 50

You're misusing statistical odds in a similar way. You have a 98% chance to fail each enhance to PEN, which gives you a (0.98^50) 36.416968008% (0.36416968008) chance to fail all 50 in a row. It's why using failstacks and/or hyper-specific techniques to maximize your RNG is important - if you had a 96% chance to fail instead (a 4% chance to succeed, 0.96^50) the odds of failing all 50 in a row drop down to 12.988579352% (0.12988579352) and if it's down to 95% - a 5% chance to succeed - it's 7.694497527% instead (0.07694497527) because any additional chance to succeed has an exponential cascading effect on how unlikely it is to fail sequentially; you'll notice that doubling the chance to succeed more than halves the chance to fail (in fact, doubling it in this case just about reduces your chance to fail all 50 to a third of what it was) meaning that even a +30 Advice of Valks has a massive positive effect on your odds.
