Thanks 
As for the transfers, even thou it’s offtopic (though fairly I think in this particular thread offtopic is better than ontopic
) it’s not so much “harmful” than “not necessary”.
So how should I explain this best… While some people might like to experiment with things, as a generalized thing you don’t put chocolate cream in your cheeseburger
right?
That’s pretty much the thing here. They had a legit technical roadblock when it came to expanding the map, so instead they choose to make a completely new map as a DLC instead of expanding the old one.
This in turn allowed them certain freedoms when it came to designing IoS. Items there no longer had to fit in with the EL map and it also gave them a good chance to experiment with things, as a result most of those things aren’t really balanced for EL and they have their own sigil mechanic like you said etc.
They then released that as a completely separate map with its own mechanics and own gear and own version of balancing, it was never designed to be merged, because they knew they can’t expand the original map.
But then suddenly people wanted to go back and forth, they even have mods facilitating transfers between clustered servers so Funcom caves in and tries to bring server transfers into the game.
Much like with a lot of things, they rush into it and not anticipate all of the potential pitfalls.
I’m pretty sure they had the best of intentions and just wanted to cater to people and boost their IoS sales a bit.
However due to the way they implemented this, it started to present technical issues, characters started to not go through to the other side and end up simply being deleted etc.
And ofc the ones who made it through quickly upset the balance of the other map, and while it’s mainly a PvP issue when it comes to balance… it’s not just… Why? Because even PvE players tend to lean towards “improvement”… so if you suddenly have eldarium weapons… then why would you care to get star metal ones?
a whole section of the map was dedicated to that on EL and obsidian and so on.
When something is significantly better then it kills the competition and variety, which pretty much made everything else feel “useless” even more so than the map already managed to do it on its own (since we already had the issue of legendary weapons dwarfing in comparison to crafted ones by high tier thralls), on top of that the progression that they messed up from the start (roughly 0.2 XP rate is what would be “normal” for a game like this, the default one is absolutely stupid and makes every single one of those iron and steel recipes pointless)
My point is… that introducing this, made even PvE worse imo. ofc others might think differently. I would love being able to travel back and forth between the maps… but I would prefer it if it’s available for everyone (whether they bought IoS or not) and I would prefer it if it was made part of the game and not as an external transfer. Then they could balance Siptah as the continuation of EL and suddenly all of that would make sense from all gameplay perspectives and they could still rebalance some higher level zones in EL to actually require the Siptah stuff.
Atm, the way transfers were… it just wasn’t a good solution imo.
That’s pretty much regarding the transfers, ofc now that they’re disabled and people gave Funcom feedback of how it is a slight bit of P2W if they’re not creating similar equipment available for free, I highly doubt we will ever see transfers return in the form they were. For one they had technical issues and data loss so that requires work, but coupled with the feedback that work is probably the lowest priority for them atm. So we might see it if they really have nothing better to do 
As for the weapon sheathing animations and why is that “important”. Funcom got some pretty serious backlash after 3.0 from the console side of things… while it was okay on PC (like really… I barely had any bugs happen in my game and everything played smooth), it was disastrous on the console front… and people are questioning why haven’t they dropped PS4 support completely if the game is unplayable on it…
So right now what they’re doing is trying to “get their act together” and somehow polish it up to where it runs fine on all consoles they support - at least by the look of it, that’s what’s happening. These animations are part of that optimization.
