Okay, this is going to be long so...
tl;dr version:
The vehicle abandon mechanism is unfair and punishes good plays, it should be either removed or reworked.
TED talk version:
I will try to be as logical and reasonable as possible here, therefore I will share my wonderful experience with it and post the pros and cons to see both sides of it
Cons:
1.) Do not reward player's good play
So my enemy microed pretty hard and lost quite a few grenadier models but he finally was able to fraust my UC. However it was abandoned and I was able to repair it up and recrewed it. It happens multiple times in different games.
(2v2) my Churchill tank was abandoned in a big fight but it was covered in its own smoke, enemy assault wave then died down, I took the opportunity to repair it back up with heavy sappers' quick repair. My enemies committed to a big push and they got almost nothing.
2.) Punish aggressive play unnecessarily
(This is an experience from my friend in 1v1) 2 su76s and a t34/76 rushed into enemy base, although he killed the king tiger, one of his su76 and t34 were abandoned and reused by his enemy. This mechanic imo makes tank play very static in this game, players only willing to camp their tanks in their own territory most of the time and why bother doing all the fancy moves, flanking into enemy territory when such a risk exists? This mechanic is just a big splash of cold water to the face telling you to fuck off.
3.) It simply does not feel gardening fair, why do I have to put an extra shot to secure the kill that I shouldve achieved??
(2v2) I tried to kill a p2 abandoned right next to an okw HQ, his kubel died and smoke from its wreckage blocked direct LOS, I then lost two 6 pounders to finish off that pesky LV because somehow they couldnt shoot it and flak HQ killed them both.
(1v1) I lost almost everything just to abandon a tiger tank in my opponent's backline, he didnt even have to spend anything to attack me later with a full health fat tiger and I gardening died. We would still be even if he had to remake the tiger with resources.
(2v2) I dived an elefant with a comet and cromwell plus coordinated barrage, both tanks died and I only managed to decrew it. It is recrewed by the other okw opponent. The wehrmacht remade elefant and we had to fight two gardening elefants at the same time in late game and I don't think anyone can win as allies at this point
(1v1) my firefly shot down a puma (yes it took a shot as powerful as a 17 pounder at half health) but it was abandoned in the walls behind Lost Glider, I then lost the game due to double puma sniping my pudding in a very meat-grinding battle.
Pros:
1.) ayy lmao tank abandon go boom
very funny mechanic lol , makes the game "interesting" omegalul
seriously up to this point if you still think this mechanic is fine, you are either a troll or you need to go see a doctor
Rant/Personal feeling:
This is gardening bullpudding and I remember every single bloody moment of it. Yea it happens rarely but it still happen from time to time, and that they often have serious impact in those games.
I feel so gardening frustrated when it happens, do I waste 30 mins into each game just to be screwed over by this bullpudding?
This "feature" is just as annoying as plane crash and I hope it is removed/rework asap
