As someone who try to help new players to do the following dungeon: AAHM / GVHM / AQ I really do not understand why you give only 5 entry PER WEEK.
Do you realize how you prevent new player to actually play those dg ? To play any of the latest DG (Kelsaik nest / forbidden arena) you had 2 or 3 days to find your roster and if you did'nt then your only choice was to Q.
Yet, even though you MAY find people due to the matchmaking ( if you wait for 30 min or more if you are not a tank) you may be kicked out of your party because they don't want to waste time with people who want to learn. Why ? Because the DG is more than 3 days old and if you have not cleared it yet you are trash \ o/.
Thus, the decision of extending low entry number to the dg aforementioned dungeon is insanely stupid. Most of the well established guilds will not bother to teach new players and without new players which can enjoy the end content and are stuck on low level dg, the chance of them quitting tera is quite high. Moreover, for player like me who do try to help people learn mechanics through normal way (because in case you forgot some people use proxy so that they won't have to learn the mechanics) it is also disadvantaging. My question is: Why the f*ck should I still help lancers, brawlers and DPS to learn the mechanics and stay for more than 1 hour in a dg (if most of my team consist of begginer) if I could just chill with other players and do it in less than 15 minutes?
=> And don't tell me "but you have extra loot if you do that" cause it works only if you use the matchmaking option and the extra loot is laughable (meaning that it is not balanced with the difficulties of having an inexperienced player but it is still nice to have it).
As such, you should double the entries : 5/10 => 10/20 , because even though your excuse is that "you stuff will be easier to upgrade" there is still the question : Okay then but what if I don't like some dg ? What if I have nothing to do on TERA because I have done all my lvl 70dg and there is nothing left to do ? (5 dg per day if you are not a tera club member)
Moreover, almost all of the top players already have their gears or are close to have them up to max lvl. This means that again there will be a striking difference between players and yet again you divide your community.
Overall, I appreciate the effort of trying to simplify the access to gears but the way of doing it is wrong. From 40/80 entries to 5/10 entries is not Ok. 5/10 could be understandable if it was EXTREME mode or if it was the last DG (like older lvl 70 dg = 10/20 entries per week and new dg=5/10 and when a newer dg is released the old one goes from 5/10 to 10/20) but for hard more it is completly stupid (even more so when there is a quarantine and people are likely stuck at home with nothing to do except playing).
