I will try my best to explain it without being condescending:
You have two types of players in PvP:
a) those who will stick to one spec, regardless of its shortcomings against a certain comp, and use it without feeling the need to respec or shuffle points/rr that much. In RoR, this would probably be a casual player.
b) those who will adapt and change their specs to best meet their opposition's comps. These are what many would call
min-maxers; or elitists, in RoR.
Now, if you chose to enter a scenario against a ranged comp with pure melee crit invested into your renown - with no dodge/disrupt, a 25% chance to be crit, and no defensive stats - then
that would be your prerogative. That is completely
your choice.
Sure! I get it: respeccing just to try and maximise your chances is boring, man! Just go with the flow; fight with what you have. If that is
your line of thinking, and
your mentality - then yes, the change to AT would have had very little/0 impact on you. However, do not suppose that the same is true of every other player - particularly those who
play to win.
Previously, one could change one's renown and mastery abilities in a WC before the SC began. You had very little time to do this: if you took too long, then your opposition would be given valuable time to go and capture all of the flags that we, players of RoR, have grown to love and cherish so much (Blood of the Black Cairn and Reikland Factory keep me playing). To add to this,
you would have to pay 5+ gold to do this, which - in the long run - can become quite expensive.
However...doing this is
my prerogative: it is up to
me if I chose to maximise my chances of winning by altering my spec/mastery/rr in some guise in order to better handle enemy team (to be honest, this is pretty basic for 6v6, so I am not sure what Starilas is going on about).
Now? You can no longer do this. I understand that it was fixed because it's a bug/wasn't functioning as it was on Live, and for fixing this bug I commend the devs. It's just for those of us that do min-max, and want to win without simply pissing into the wind and saying 'oh well! maybe this max parry max melee crit spec will help against those 6/7 sorcerers and magi, maybe it won't! #swag #yolo!', it is a very big loss.
Instead, we will now have to
travel back to capital city, wait for everyone to join and tell you what comp your up against, so that you can then respec, join late, rinse-repeat.... Roaming RVR will be disadvantageous in a way, as you have no career trainers in proximity - should a sc pop.
All we ask (because I do believe a lot of people share my view on this) is that mastery/career trainers are added into scenarios (or certain scenarios, if deemed too laborious a task). Doing so would have no effect whatsoever on the vast majority of people voicing their opposition to this, as they are (by and large) casual players who do not feel the need to min-max (nothing wrong with this; just an observation), or go all out to try and maximise chances of winning. But, it would afford teams that are learning and discovering methods of countering opposition the option to quickly adjust and reshuffle a few points, so as to give them the best chances of winning.
THIS is balanced PvP, i.e. not starting off at an immediate disadvantage due to being unable to respec accordingly.
@Panzer: nothing against you, but I honestly can't remember the last time our skepta/csi/simba group lost to you. Last I remember, you guys were talking the Isha bauble which made us all /lol in comms.

Shame really because you guys were always a good fight, then you sort of dissipated/disbanded?
