I don't know about you, but I'm an old player and as many, I know the issues with the Caligor raid. I started playing again on Jotunheim. I'm playing archer and of course I want to have a Demon Hunter. Though, I'm not interested in PVP.
The issues are to firstly get into Caligor raid, which was impossible for me even though I was there an hour early. On the way I was killed several times by those who camped at the portal to the unknown (I don't know how it is called in English, since I play in German). And when I achived that, and sat in my Miniland to at least not get killed anymore, I can't even click on the portal since there are so many. Today I tried a different approach as well - I tried the portal above where the mobs are, but even there were people camping and killing.
I only got to Caligor once, but only by using my jaja and getting invisible (tho, I was killed many times too, since being invisible doesn't help anymore). But because of the transformation time and lag, I was not able to get enough activity points.
As I said, I'm not a person for pvp. I like to play pve. It's alright, that a4 is a pvp area. But it's not right, that you are forced to be part of pvp if you want to have sp7. Every other sp is achievable with no issues. Only sp7 is that difficult. Firstly, because getting into Caligor is limited and, on the other hand, you have to avoid getting killed.
So, my suggestion is pointing to that. I wouldn't want to take away the Caligor raid, since there are people who enjoy pvp. But what about making ways available to get Caligor's spirit to exchange it into a Sp7. Like there are raids, where Caligor is part of. Like Laurena. There is a caligor spawn.
Why not making Caligor's spirit a reward in Laurena raid from the box? That way, people who don't like to do pvp, are able to achieve sp7. And making raids like Laurena more attractive. I know a lot of people, who never even did that raid, since it seems so complicated.
