Most away concessions aren’t really considerably less…….most of ours will be seniors or 18-21/24 (if the latter get any concession at all), and they’re usually £25 (or more - think Villa was 29.50) vs £30 for full price (except Palace who are generously charging £22).I guess you could look at it that way, but everyone in tier 1 can already do that and just take a loss and leave the seat empty - we're talking £30 in most cases, and considerably less for concessions (of which we have plenty). All popular games go to tier 2 anyway and rarely beyond that. At least this way, it is possible for those in the relevant tiers to pick up a ticket that they may have missed out on. The reality is that those in tier 2 are often in a binfest for scraps anyway - see Brentford.
This is good for everyone imo even if there are some loopholes here and there. Nothing is perfect.
