I actually joined TAW's Escape From Tarkov division awhile back. From my personal opinion TAW's rules were very unfair. I know that TAW are a bunch of separate divisions bunched into one umbrella but the experience was not pleasant for me at all. There was a once a week mandatory meeting to "prove" you were an active player. For instance; our meeting was Saturday nights @ 8:00 EST (ball park). I was on Teamspeak all week conversing with Officers and members of the clan. But I did not get credit for being active in the clan because I missed a 20 minute "team" meeting on a Saturday. There was no exceptions to the rule and the reasoning was that the clan lasted so long due to that rule. There are different times for meetings depending on the time zone, but it is majority rules. I understand this clan is ran with a Militaristic style, but at times it is not fair. You can set "excuses" on the website stating why you cannot attend, but you only get so many chances before you are discharged. Certainly not my cup of tea.
Just stating my experience with TAW. If you can make the times I am sure the community is great, but there are rules for everything. Review the "Boot camp" PowePoint they give you before you join. Goodluck and Cheers.
