Hiya.
I chose "No, I do not allow feats, even though I think they are considered necessary by most players", even though I *am* allowing Feats in the current game we are playing. I didn't allow them when we first played, then I allowed them, then I didn't, now for this mini-campaign I'm allowing them, but with some changes. I'm pretty sure my next and following campaigns will be flat out "No Feats".
We are finding them to be a mixed bag. One one hand, if you allow the optional Human thing where they get a Feat at level 1...it can REALLY make a difference. Now that the PC's all just hit level 4 in my current game, they all took a Feat, and I'm not seeing nearly as large a difference...although it does feel like the players are deliberately looking for some way to "make" an opportunity present itself so that they can use their Feat.
For example, one Cleric took the Heavy Armor Mastery Feat. Before, he would work with the other players to plan a means of attack against a room full of kobolds...but now, he just wades in and lets everyone else fend for themselves. I've found the other players change their characters "personality" as soon as they got a Feat. Maybe not on purpose, maybe subconsciously, but there is a definite shift in attitude/choice when their particular Feat may come into play. It is primarily for this reason that I'm not allowing Feats anymore after this campaign.
Actually...I shouldn't say "not allowing". I should say "By default, no...but...". I
may allow a Feat to be obtained by a PC, but it will not be a simple matter of "Ding! I gained a level! I'm taking Uber-Feat Number 6!". Feats will be "special abilities that only a few rare individuals/groups/secret-orders/guilds/etc know". If you want to learn one of these things, you'll have to work for it though role-playing...not just killing stuff to get enough XP.
A lot of the Feats will be modified as well. Crossbow Expert, it takes two hands to load...I don't care what the rules say. Any of the -5/+10 Feats will be downgraded to -5/+5 and if used can NEVER be used with Advantage. With Alert, the second bullet point about never being Surprised is nixed. And many other Feat changes.
As far as my group goes... nobody ever liked Feats in the first place (talking about 3.x and PF). I think one of my players didn't much care one way or another, initially, but once we had been playing for a few years even he got sick of them. Alas, it was pretty much impossible to get rid of Feats in 3.x/PF so we were forced to play with them. When some ridiculous combo showed up (usually not on purpose), it was like getting a dozen paper-cuts and then pouring lemon juice on them. Ugh! So, now that Feats are
OPTIONAL in 5e, I'm taking full advantage of that and just saying "No!"...mostly.
