Hello there, 
I am a casual player for a long time now, about 4.7k hours and have always liked playing this game, but this event that PA has designed just rubs me the wrong way...

The Tarnished Sword has nice rewards and some server rewards, which you only get by enhancing it to pri, but the problem is and PA has been able to calculate this beforehand, that the chances that casual players actually reach PRI are very low. We recieved a total of 240 orbs and additional 200 orbs in a hotfix since PA clearly saw that people weren't reaching PRI, but 12 orbs a day when you need 30/40/50 for a tap, is just not enough..

If you don't have the time to grind/lifeskill regulary or don't like to leave your computer on overnight to do AFK-Fishing, then you have very little chance of actually completing the Tarnished Sword and getting all the rewards (Yes I am aware you need to reach PRI for all the rewards). These server events can be nice to bring the community towards a common goal, but the way this one in particular is designed, only creates a divide for casual players to not bother, since clearly PA doesn't care about casual players if they allow events like this to occur. The daily login rewards for the orbs should have been way higher, at least 50 a day, and maybe even more because of the rng chance of straight up failing the maximum amount of times for multiple enhancing tiers. 

Besides the point above I would like to say, I am a casual player, but I still log in on a daily basis, long enough to obtain all the orbs. But being a casual player does not mean PA gets a free pass to overlook you in events such as these. Even though I couldn't grind of afk-fish on a regular basis, I have put effort in to try to get to PRI with the Tarnished Sword, but have failed due to a lack of orbs and bad rng. Effort should be rewarded, even if effort of a casual player looks different than the effort of a hardcore player, the effort was still made.
I have never made a forum post before, but this event rubs me the wrong way and feels like a foreboding sign that if I do not raise my voice, they will continue with this design, and the game will only be poorer for it.  

I doubt PA even bothers to read these forums or does much with it, but I am still posting it with good faith. This event has been a big middle finger from PA towards the casual player base and I hope they realise the mistake they made and fix it asap. Give everyone the server rewards.

This. I've noticed this problem with not just this event, but a few of the others that involve collecting a special event item from grinding/gathering/fishing...they either don't drop often enough, or you need so many of them that the rate at which they drop is simply not enough unless you grind all the time, AFK fish, and/or have login/time rewards bolstering it.

my problems with this is the rarity of the orbs needed to enhance. i came back mid-event and didnt get the full rewards and have had to rely on gathering/fishing to get them. i've failed 14-15 twice now and at 50 a pop its is VERY expensisive and frustrating. it took me a day and a half to get the last 50. hotfix an increased droprate at the very least.

Drop rate for the orbs life skilling was appaling. Had to overnight fish to get enough.
