I am not a Plarium sympathizer by any means, but there's a lot that I don't necessarily agree with around what you are saying:
1. You are dropping a lot more 5* and 6* rare artifacts in the dungeons,
Check out https://i.imgur.com/wGqEI3u.jpeg which is what I have been referencing for drop rates for quite a while now. Statistically rare items account for 55% of items dropped, even at stage 25 for dungeons. Earlier stages can be 70%.
2. We just had a 2X Savage drop in the fire knights castle, I played 50 Multi plays and got 0 pieces of Savage gear.
Putting aside sample bias, I suspect that you have your runs filtered to automatically sell 5 star or lower gear. If this is the case, it would be possible that you are getting a lot of Savage gear, but are just auto-selling it.
Also note that 2x Savage doesn't really equate to twice as much savage gear. It just means that the savage chance itself will increase by 2x. Without any event, each gear for Fire Knight has a 1 in 9 chance of dropping. With the 2x Savage event, then Savage appears twice, so it means each piece of gear set has a 1 in 10 chance, while Savage has a 2 in 10 chance (or 1 in 5, or 20%). It is still very much possible not to get any Savage gear
3. The last two fusion events were horrible at best. Only End game players can fuse the hero.
The Morrigaine one was pretty bad in the sense that if you missed a single rare you had to miss the entire fusion, but resource wise, I believe that the fusion events have been consistent with previous ones. You need to save up and prepare for fusion events, otherwise you won't be able to do them. Hell Hades (a Raid content creator) has completed a few with a new account so it is definitely possible for non-end game players to do these if they prepare for it.
4. It now takes a lot more books to upgrade an Epic or Legendary.
Not really sure where this is coming from and keen to get some examples. Morrigaine (the most recent one) needs 10 Legendary books to finish, which I think is statistically quite low or average. Orn (one of the new epics) requires 13 books, but Duedan requires 10. The average I feel is around 10 to 12 for champions, and usually the new ones are around that
5. This is a game, Not a job or a lifestyle, While I like to play the game, I don't have 10 hours a day to complete the Tournaments and/or Events.
I think this is probably the biggest challenge that you have. As much as this game loves to think that it is, it is not a PvP game. Pretty much everything that you are doing in the game is at your own pace, so you need to start approaching the game at that mindset.
You should be picking your battles and targeting an area for improvement, and not spending 10 hours a day every day in the game to get all of the content done. You don't need to do every event and tournament. You don't even need to do all of the daily quests and advanced quests. I personally don't. I just focus on the ones that matter to me.
Edit: I don't even view the tournaments as PvP, as I expect that I will never be able to compete with the top players due to how much they spend. Tournaments and Events are for milestone rewards for me. If they are interesting, then I will build a team for them. If not, then I will skip
