I rarely make quality of life adjustment requests, but in this case, I think the drop rates of the High Tier Battlefields should be increased to at least one random gear drop per victorious run, at least on the Normal 119 difficulty.
I'm suggesting this because there is comparable content in the game right now- namely Escha NMs- that have guaranteed gear drops, even if it's not always necessarily the one you want. In many cases, the price to enter these battlefields (however easy it is to come by merits these days) is still higher than it is to spawn an Escha tier I NM.
The drop rates for High Tier Battlefields on Normal seems to be in the range of 1/20, which I think is unacceptably low, considering much of the gear is outclassed anyway these days. Still, some of these items are great sidegrades. Many of the weapons in these battlefields will also go a long way in getting returning players back on their feet, yet still have to work on getting the current newer, better weapons. For a returning player with no outside help, these battlefields actually seem like pretty appropriate challenges for somebody with a few trusts and only Eminent gear.
